Principle of SEW Brakes Basic design Principle of SEW Brakes. Basic design The SEW brake is an electromagnetic disk brake with a DC coil that is released electrically and braked using spring force. The system meets all fundamental safety requirements: the brake is applied automatically if the power fails. The principal parts of the brake system are the brake coil itself [8] (accelerator coil + coil section = holding coil), comprising the brake coil body [9] with an encapsulated winding and a tap, the moving pressure plate [6], the brake springs [7], the brake disk [] and the brake endshield []. A characteristic feature of SEW brakes is their very short design: the brake endshield is a part of both the motor and the brake. The integrated design of the SEW brakemotor makes for particularly compact and sturdy solutions.. Basic functions In contrast to other disk brakes with a DC coil, the SEW brakes operate with a two coil system. The pressure plate [6] is forced against the brake disk [] by the brake springs [7] when the electromagnet is deenergized. The motor is slowed down. The following brake springs are used as required: Brake springs with normal spring force: Color: black/silver for DT/DV and for DR motors Brake springs with reduced spring force: Color: red for DT/DV motors Color: blue for DR motors The number and type of normal brake springs or the combination of normal and reduced brake springs [7] determine the braking torque. When the brake coil [8] is connected to the corresponding DC voltage, the force of the brake springs [] is overcome by magnetic force [], thereby bringing the pressure plate into contact with the magnet. The brake disk moves clear and the rotor can turn.

Principle of SEW Brakes SEW brake systems in detail.. BE.. brake The BE.. brake is used for motors DR.7 - DR.5. In the smaller DR.7 and DR.80 motors, the brake operates according to the principle of the BM(G), i.e. brake integrated directly on the endshield. The principle of the modular brake on a friction disk begins starting at motor size DR.90. The modular brake allows for mounting of up to three brake sizes to one motor. The B-side endshield is to be regarded like a connecting flange, which accommodates the BE brake pre-mounted on a friction disk. Although the integrated brake is mounted on a complete brake endshield, it can be dimensioned to suit specific requirements, just like the modular brake.

DUB0A (Diagnostic Unit Brake) is a diagnostic unit used for reliable monitoring of the brake function and brake lining wear. Function monitoring: The function monitoring system signals whether the brake releases properly. Wear monitoring: The wear monitoring system signals when the brake has reached a specified wear limit. However, the brake remains functional. Wear and function monitoring: The two integrated microswitches are identical and are set at the factory. They are used as normally open contacts (function monitoring) or as normally closed contacts (wear monitoring).

Principle of SEW Brakes SEW brake systems in detail..6 BR.. brake The BR.. brake is installed in CM...BR synchronous servomotors and DAS...BR ASEPTIC motors. The SEW brakes transfer the braking torque to two friction surfaces. The brake is released when the brake coil [9] is energized with direct current. As a result, the pressure plate [0] is pulled onto the brake coil body. The brake disk [], which is connected to the motor shaft by a driver [], is released. When the brake coil is deenergized, the brake springs [8] determine the braking torque generated between the brake disk and the brake bearing end shield [] or pressure plate.

kva i P f n Hz Numerous Possibilities Using Modular Brake Controls SEW brake systems in detail Numerous Possibilities Using Modular Brake Controls The SEW brake system, just like the entire product range of SEW-EURODRIVE, has a modular structure. The modular concept consisting of electronic and mechanical components permits a wide variety of tasks to be accomplished. In the mechanical range of the modular units, there are various types to be considered, such as adjustable braking torques and additional options. Electronic components, on the other hand, make different control systems and functions available, such as high-speed excitation or a heating function. In this way, all SEW brake systems share one basic principle, which is adapted to the broadest variety of possible uses by combining elements from the modular concept. The following table gives an overview of the possible combinations of brakes and controls and the resulting properties.

Numerous Possibilities Using Modular Brake Controls Particularly short response times at switch-on kva i P n f Hz The following features are explained in more detail in the next sections: Particularly short response times at switch-on Particularly short response times at switch-off Particularly safe High stopping accuracy High starting frequency possible Low noise level High thermal load possible Low and fluctuating ambient temperatures possible. Particularly short response times at switch-on A special brake control ensures that only the accelerator coil is switched on first, followed by the holding coil (entire coil). The powerful impulse magnetization (high acceleration current) of the accelerator coil results in a very short response time, particularly in large brakes, without reaching the saturation limit. The brake disk moves clear very quickly, and the motor starts up with hardly any braking losses.

kva i P f n Hz Numerous Possibilities Using Modular Brake Controls Particularly short response times at switch-on The particularly short response times of SEW brakes lead to faster motor startup time and minimum start-up heating, which reduces energy consumption and brake wear during startup (see following figure). Benefits for the user: very high starting frequency and a long brake service life.

The braking magnet is now only magnetized to such an extent (weak holding current) as to ensure that the pressure plate is held open with a sufficient degree of safety and minimum brake heating. Advantages: A fast opening of the brake can lead to the motor starting quickly, as the above figure shows. Consequently, the motor starts up only minimally against the closed brake (time up to the end of t ), reducing the heating up of the motor significantly. This makes it possible to have more cycle times per hour. Drive Engineering Practical Implementation SEW Disk Brakes
Numerous Possibilities Using Modular Brake Controls High starting frequency possible kva i P f n Hz. High starting frequency possible Brakemotors often demand a high starting frequency and significant external mass moments of inertia. In addition to the basic thermal suitability of the motor, the brake needs to have a response time t short enough to ensure that it is already released when the motor starts. At the same time, the acceleration required for the mass moment of inertia also has to be taken into account. Without the usual startup phase when the brake is still applied, the temperature and wear balance of the SEW brake permits a high starting frequency. Brakes from BMG8 BMG and BE5 BE are designed for a high starting frequency as standard. The table below shows that, in addition to BGE (BME) and BSG, the BSR, R, BMH, BMK and BMP brake controls also have properties for shortening the response time in addition to their other functions.

kva i P f n Hz Numerous Possibilities Using Modular Brake Controls Particularly short response times at switch-off. Particularly short response times at switch-off This means de-excitation occurs very rapidly when the coil is switched off, so the brake is applied with a very fast response time, particularly with large brakes. User benefits: very short braking distance with high repeat accuracy and a high degree of safety, e.g. for applications involving hoist drives.

Numerous Possibilities Using Modular Brake Controls Particularly short response times at switch-off kva i P f n Hz The response time for the application of the brake depends to a significant degree on how rapidly the energy stored in the brake coil is dissipated when the power supply is switched off. A free-wheeling diode is used to dissipate the energy for a cut-off in the circuit. The current decays according to an e-function. The current dissipates much more rapidly via a varistor when the DC and circuits are cut-off at the same time as the coil s DC circuit. The response time is significantly shorter. Conventionally, cut-off in the DC and circuits is implemented using an additional contact on the brake contactor (suitable for an inductive load). M TS BS V 589009 Electronics from SEW-EURODRIVE for rapid application of the brake: Under certain conditions, you can also use SR and UR electronic relays for interrupting the DC circuit. The SR (current relay) electronic relay is used for constant-speed drives supplied from the motor terminal board. The UR (voltage relay) electronic relay is used for variable-speed drives with separate voltage supply. Advantages: The faster the magnetic field is dissipated, which causes the braking effect to begin, the earlier the existing movement will be intercepted. In this way, a fast-acting brake increases the safety of the system. For example, hoists can be secured quickly in case of power failure, thus preventing accidents. The fast application of the brake also increases the braking and positioning accuracy required in uncontrolled operation. Drive Engineering Practical Implementation SEW Disk Brakes 7
kva i P f n Hz Numerous Possibilities Using Modular Brake Controls High stopping accuracy. High stopping accuracy Positioning systems require high stopping accuracy. Due to their mechanical principle, the degree of wear on the linings, and on-site basic physical conditions, brakemotors are subject to an empirically determined braking distance variation of ±%. The shorter the response times (see page 6), the smaller the absolute value of the variation. Cut-off in the DC and circuits makes it possible to shorten the brake application time t considerably. Cut-off in the DC and circuits with mechanical contact: The sections Basic functions (see page 8) and Standard brake control (see page ) have already referred to the possibility of achieving this solution by conventional means by using an extra contact. Cut-off in the DC and circuits with electronic relay in the terminal box: The BSR and R brake controls offer particularly elegant possibilities involving an electronic, wear-free contact at the same time as minimum wiring work (see page and following). Both control systems are made up of BGE (BG for size 6) and either the SR current relay or UR voltage relay. BSR is only suitable for single-speed motors. R can be installed universally if it has a separate power supply. When ordering the brakemotor, it is sufficient to specify BSR and R in conjunction with the motor or brake voltage. The SEW order processing system assigns a suitable relay. The proper relays for possible retrofitting and those for motor and voltage can be found in the sections Principle and selection of the BSR/R brake control. The electronic relays can switch up to A brake current, thereby limiting the selection to BSR and R. 8 Drive Engineering Practical Implementation SEW Disk Brakes
Numerous Possibilities Using Modular Brake Controls Particularly safe kva i P f n Hz.5 Particularly safe Tried and tested design components and brake controls tested in trial applications ensure that the SEW brake has a high degree of operational safety. Due to the fail-safe principle, the brake is closed by spring force if the coil is not under current. Consequently, the brake always goes back to a safe condition in case of power failure. Advantages: The sturdy mechanical components of the brake are designed to withstand several times the rated load. Because of SEW-EURODRIVE s great deal of experience, the brake linings are carefully adapted to meet customer needs and have proven themselves in many years of operation. In addition to reliable standard brake controls, one can also select safety-oriented control systems, such as BST (see the publication Safety-Oriented BST Brake Module )..6 Low noise level Many applications in the power range up to approx. 5.5 kw (-pole) require particularly quiet brakemotors to reduce noise pollution. SEW-EURODRIVE implements special design measures to meet these requirements as standard for all brakemotors up to size DVS and for all motors from the DR modular series without affecting the special dynamic features of the brake system. Advantages: The surrounding area will not affected by noise caused by brakes. The noise damping does not change the time the brake requires for switching on and off. Possible places of use for noise-damping brakes could be, for example, the theater. Because of their quiet application and opening, the brakes would not be heard by the audience..7 High thermal load possible In addition to the basic considerations, elevated ambient temperature, insufficient supply of cooling air and/or thermal class 80 (H) are reasons for installing the brake control in the control cabinet. Only brake controls with electronic switching are used in order to ensure reliable switching at higher winding temperatures in the brake. The use of BGE, BME or BSG instead of BG, BMS or DC V direct connection is prescribed for the special case represented by electronic brake release when motor at standstill for brake sizes BMG05 BMG and brake sizes BE05 BE. Special designs of brakemotors for increased thermal loading must be equipped with brake controls in the control cabinet. Drive Engineering Practical Implementation SEW Disk Brakes 9
kva i P f n Hz Numerous Possibilities Using Modular Brake Controls Low and fluctuating ambient temperatures possible.8 Low and fluctuating ambient temperatures possible Brakemotors for low and fluctuating ambient temperatures, e.g. for use outdoors, are exposed to the dangers of condensation and icing. Functional limitations due to corrosion and ice can be counteracted by using the BMH brake control with the additional function anti-condensation heating. The heating function is activated externally. As soon as the brake has been applied and the heating function switched on during lengthy breaks, both coil sections of the SEW brake system are supplied with reduced voltage in an inverse-parallel connection by a thyristor operating at a reduced control factor setting. On the one hand, this practically eliminates the induction effect (brake does not release). On the other hand, it gives rise to heating in the coil system, increasing the temperature by approx. 5 K in relation to the ambient temperature. The heating function (via K6 in the sample circuits) must be ended before the brake starts its normal switching function again. The BMH brake control, which is available for all motor sizes and is installed only in the control cabinet, provides the anti-condensation heating. Brakes with the BMH brake control can be used in this way with a reduced functional range at temperatures of -0 to +00 C..9 Direct control using a frequency inverter The BMK and BMV brake controls serve as units that can be directly controlled using the brake command of a frequency inverter. No other switching elements are required. BMK and BMV brake controls energize the brake as soon as the power supply and a DC V control signal are present. The releasing and application of the brake occurs with an especially short reaction time. For safety reasons, all poles must be switched off upon an emergency stop. 0 Drive Engineering Practical Implementation SEW Disk Brakes
Brake Controls in Detail Standard brake control 5 5 Brake Controls in Detail Various brake controls are available for controlling disk brakes with a DC coil, depending on the requirements and the operating conditions. All brake controls are fitted as standard with varistors to protect against overvoltage. The brake controls are either installed directly in the wiring space on the motor or in the control cabinet. For motors of thermal class 80 (H) and explosion-proof motors (edt..bc), the control system must be installed in the control cabinet. Various brake controls for installation in the terminal box or in the control cabinet mean that the optimum solution can be found for all applications and conditions. The standard type is supplied unless particular requirements are made. 5. Standard brake control As standard, DT/DV...BM(G) brakemotors are supplied with an installed BG/BGE brake control for the connection or an installed BS/BSG control unit for the DC V and terminal box connection. The standard type is delivered ready for connection. The motor connection voltage and the brake voltage are usually specified by the customer.

5 Brake Controls in Detail Standard brake control For brake applications with higher starting frequencies, different brake controls are used. Either cut-off in the circuit or cut-off in both the DC and circuits is possible with standard versions for connection. The brake voltage can either be supplied separately (particularly with multi-speed motors) or taken directly from the motor terminal board (with single-speed motors). The response times t I for cut-off in the circuit (see page 06) apply to the separate power supply. With the terminal board connection, switching the motor off with remanent energization leads to a further delay before the brake is applied. The specified brake controls have powerful overvoltage protection for the brake coil and switching contact. No brake control is supplied with the standard version for DC V voltage supply of DT56..BMG and DR6..BR motors. The customer must install suitable overvoltage protection.

Brake Controls in Detail Principle and selection of the BSR brake control 5 5. Principle and selection of the BSR brake control The BSR brake control combines the BGE control unit with an electrical current relay. With BSR, the BGE (BG for DR6) is supplied with voltage directly from the terminal board of a single-speed motor, which means that it does not need a special supply cable. When the motor is disconnected, the motor current is interrupted practically instantaneously and is used for cut-off in the DC circuit of the brake coil via the SR current relay. This feature results in particularly fast brake application despite the residual voltage at the motor terminal board and in the brake control (see page 67). The brake voltage is defined automatically on the basis of the motor phase voltage without further customer data (e.g. motor 0 V/00 V, brake 0 V). As an option, the brake coil can also be configured for the line-to-line voltage (e.g. motor 00 V, brake 00 V). The allocation of current relay and brake rectifier is made in the order depending on the specified motor and brake voltages. The following table shows the allocation of SR current relay to the rated motor current I N [A] in Õ connection and the maximum holding current of the brake I Hmax [A]. I Hmax = I H.

5 Brake Controls in Detail Principle and selection of the R brake control 5. Principle and selection of the R brake control The R brake control combines the BGE (BG for DR6) control unit with an electronic voltage relay. In this case, the BGE (BG for DR6) control unit has a separate voltage supply because there is no constant voltage at the motor terminal board (multi-speed motors, motor with frequency inverters) and because the remanence voltage of the motor (single-speed motor) would cause a delay in the brake application time. With cutoff in the circuit, the UR voltage relay triggers cut-off in the DC circuit of the brake coil almost instantaneously and the brake is applied especially quickly. The brake voltage is defined automatically on the basis of the motor phase voltage without further customer data. Optionally, other brake voltages can be defined according to the following table.

The following aspects favor control cabinet installation: Unfavorable ambient conditions at the motor (e.g. motor with thermal class 80 H, high ambient temperature > 0 C, low ambient temperatures, etc.) Connections with cut-off in the DC circuit by means of a switch contact are less complicated to install in the control cabinet Easier access to the brake control for service purposes When the brake control is installed in the control cabinet, three cables must always be routed between the brake coil and the control.

Brake Controls in Detail Brake control in the wiring space 5 5.5 Brake control in the wiring space The supply voltage for brakes with an connection is either supplied separately or taken from the supply system of the motor in the wiring space. The supply can come from the motor supply voltage only when motors with a fixed speed are used. The supply voltage for the brake must be supplied separately with multi-speed motors and for operation with a frequency inverter. Furthermore, bear in mind that the brake response is delayed by the residual voltage of the motor if the brake is powered by the motor supply voltage. The brake application time t l for cut-off in the circuit, specified in the brake s technical data, applies to a separate supply only. 5.5.

For detailed information on selecting the size of the brakemotor and calculating the braking data, refer to the volume Project Planning for Drives from the series Drive Engineering - Practical Implementation. 6.. Selecting the brake The brake suitable for the relevant application is selected by means of the following main criteria: Required braking torque Required working capacity Braking torque The braking torque is usually selected according to the required deceleration. Braking torque in hoist applications The selected braking torque must be greater than the maximum load torque by at least factor. When using the brake purely as a holding brake without any braking work, a minimum factor of.5 must be observed due to the lack of regeneration opportunity for the brake linings. Working capacity The brake s ability to function is determined by the following criteria: Permitted work done W max per braking operation Total permitted braking work W Insp until inspection/maintenance of the brake The permitted work done W max and the total permitted braking work W Insp can be determined using the diagrams in the Technical Data section. 0 Drive Engineering Practical Implementation SEW Disk Brakes

This prevents the motor from attaining excessively high temperatures. The starting frequency is seconds per pulsing for a cyclic duration factor of 60%.

Now the brake itself will be checked. The BE5 brake can deliver up to 55 Nm of braking torque, but it is set to 0 Nm (ca. x M L ). The braking torque is therefore OK.

This only applies for horizontal and rotary motion as well as upwards vertical movement. A - must be there for vertical movement downwards.

The following value can be derived from the diagram: W max =,00 J. This step satisfies the condition,00 J > 5 J. Therefore, the brake can withstand the load from the resulting braking work.

The brake must now be set to the minimum air gap again as described in the operating instructions. As an alternative to the available BE5 brake, it is possible under certain circumstances to use the BE brake. For this, the required braking torque M B must be  0 Nm. Their maximum braking work W max (,600 J) is sufficient if the peripheral conditions are the same. 6. Determine the brake voltage The brake voltage should always be selected on the basis of the available supply voltage or motor operating voltage. This means the user is always guaranteed the most cost-effective installation for lower braking currents. In the case of multi-voltage versions for which the supply voltage has not been defined when the motor is purchased, the lower voltage must be selected in each case in order to achieve feasible connection conditions when the brake control is installed in the terminal box. Extra-low voltages are often unavoidable for reasons of safety. However, they require a considerably greater investment in cables, switchgear, transformers/power-supply units as well as rectifiers and overvoltage protection (e.g. for direct DC V supply) than is the case for line voltage supply connections. With the exception of BG and BMS, the maximum current flowing when the brake is released is 8.5 times the holding current. The voltage at the brake coil must not drop below 90% of the rated voltage. NOTICE Uncontrolled application of the brake. Potential damage to property. Use larger cable cross sections. Use high-capacity switchgear and transformers/power supplies. Use a larger rectifier. 6 Drive Engineering Practical Implementation SEW Disk Brakes

6 Project Planning Information Selecting the brake contactor b) Routing information: Unless they are shielded, brake supply cables must always be routed separately from other power cables with phased currents. Ensure adequate equipotential bonding between the drive and the control cabinet (for an example, see EMC in Drive Engineering from Drive Engineering Practical Implementation ). In particular, power cables with phased currents include: Output cables from frequency inverters and servo controllers, soft-start units and brake units Supply cables to braking resistors 6. Selecting the brake contactor NOTICE Switching the DC voltage using unsuited contacts. Possible damage to the brake rectifier. As switchgear for the brake voltage and the DC voltage cut-off, use either special direct current contactors or adapted contactors in utilization category - according to EN 6097--. The brake contactor for mains operation is selected as follows: For the standard voltages 0 V or 00 V, a power contactor with a rated power of. kw or kw for - operation is selected. The contactor is configured for DC- operation with DC V. When applications require cut-off in the DC and circuits for the brake, it is a good idea to install SEW switchgear to perform this task. 6.. Control cabinet installation Brake rectifiers (BMP, BMV and BMK), which perform the cut-off in the DC circuit internally, have been specially designed for this purpose. 8 Drive Engineering Practical Implementation SEW Disk Brakes
Project Planning Information Selecting the brake contactor 6 6.. Terminal box installation The current and voltage relays (SRx and URx), which are mounted directly on the motor, perform the same task. Advantages compared to switch contacts: Special contactors with four - contacts are not required. The contact for the direct current separation is subjected to heavy loads and, therefore, to a high degree of wear. The electronic switches, however, function without any wear. Customers do not have to perform any additional wiring. Current and voltage relays are delivered already wired from the factory. For BMP and BMK rectifiers, only the power supply and the brake coils have to be connected. Two additional conductors between the motor and control cabinet are no longer required. No additional interference emission from contact bounce when the brake is cut-off in the DC circuit. 6.. Semi-conductor relay Semi-conductor relays with RC protection circuits are not suitable for switching brake rectifiers (with the exception of BG and BMS). NOTICE Brake no longer releases.

6 Project Planning Information Important design information 6.5 Important design information a) EMC (Electromagnetic compatibility) SEW brakemotors comply with the relevant EMC generic standards when operated in accordance with their designated use in continuous duty connected to mains power. Additional instructions in the frequency inverter documentation must also be taken into account for operation with frequency inverters. The EMC instructions in the servo controller documentation must also be taken into account for the operation of SEW servomotors with a brake. The instructions on laying cables (see page 7) must always be adhered to. b) Connection type The electrical design team and, in particular the installation and startup personnel, must be given detailed information on the connection type and the intended brake function. Maintaining certain brake application times may be relevant to safety. The decision to implement cut-off in the circuit or cut-off in the DC and circuits must be passed on clearly and unambiguously to the people undertaking the work. The brake reaction times t I (see page 06 and following pages) for cut-off in the circuit apply only if there is a separate voltage supply. The times are longer if the brake is connected to the terminal board of the motor. BG and BGE are always supplied wired up for cut-off in the circuit in the terminal box. The blue wire from the brake coil must be moved from terminal 5 of the rectifier to terminal for cut-off in the and DC circuits. An additional contactor (SR/UR) must also be connected between terminals and 5. c) Maintenance intervals The time to maintenance is determined on the basis of the expected brake wear. This value is important for setting up the maintenance schedule for the machine to be used by the customer s service personnel (machine documentation). d) Measuring principles The following points must be observed during service measurements on the brakes: The values for DC voltage specified in the data sheets only apply if brakes are supplied with DC voltage from an external source without an SEW brake control. Due to the fact that the freewheeling arm only extends over the coil section, the DC voltage that can be measured during operation with the SEW-EURODRIVE brake control is 0% to 0% lower than the normal one-way rectification when the freewheeling arm extends over the entire coil. 50 Drive Engineering Practical Implementation SEW Disk Brakes

Overview CAUTION System stop because the brake no longer releases. Injuries. The voltage supply to the brake must always be routed separately. The supply voltage cannot be taken from the terminal board of the motor due to the variable motor supply voltage. Under normal circumstances in the frequency inverter mode of the motor, the mechanical brake only has the characteristics of a holding brake for holding a position which has been reached and of a security brake for an emergency (emergency stop). Consequently, its size is determined by a defined number of emergency stop braking operations of the drive at full load from maximum speed. The brake command is always issued to the frequency inverter simultaneously with the stop command without any delay. It is beneficial and recommended for this command to be generated by the frequency inverter itself. Internal interlocks in the frequency inverter ensure that the precise moment is selected. This allows the load to be safely taken over by the mechanical brake, thereby avoiding, for example, any sag on hoist drives. The table below gives an overview of all brake controls possible in conjunction with frequency inverter supply to the motor.

Overview DFS56..B Brake B of the DFS servomotor is a permanent magnet brake with a standard supply voltage of DC V. It operates with an unchanging braking torque of.5 Nm (DFS56M and DFS56L) and 5 Nm (DFS56H). The brake cannot be retrofitted and operates without a brake rectifier or a brake control unit. The overvoltage protection must be implemented by the customer, for example using varistors. The brake can be used in all speed classes.

DFS56..B, CMP..BP, CMD.. BP und CM..BR Servomotors with Brake Overview 8 CM7..BR - CM..BR The BR brakes of the CM7 to CM..BR servomotors can be supplied with voltage from the control cabinet via a separate plug connector or via terminal boxes. The B-side integration of the brake into the motor housing makes for a particularly compact design. Servomotors can also be supplied with the manual brake release option. The various brake controls and the possibility to connect to 0 V, 0 V, 00 V, 60 V as well as to DC V mean that this characteristic emergency stop and holding brake can also be used in all applications involving highly dynamic qualities. Supplying the brake with DC voltage directly without the SEW switching electronics is not approved. With servo drives, the brake command is generated in the MOVIAXIS or MOVIDRIVE servo inverter and is used for switching the brake with a suitable brake contactor. Depending on the motor type, the BR brakes are available with two braking torques, M B and M B. The higher braking torque ( to x M 0 ) is used for hoist operation for reasons of safety. With this brake, as well, the size is determined by the required number of possible emergency braking operations at full load from maximum speed.
