7 Introducing the air motor The air motor is one of the toughest and most versatile power units available to today s design engineer. It is easy to control over a wide speed range, and it produces maximum torque where it is often most needed at start up. It should be noted that all vane air motors produce a variable starting torque, due to the position of the vanes in the motor when it is started. The variation differs between motor types and must be checked on an individual basis. The power that an air motor produces is a function of torque and speed. All ungoverned air motors produce the same characteristic power curve, with maximum power occurring at around 0% of the free speed. The torque produced at this point is often referred to as torque at maximum output. The performance curves for an ungoverned air motor operating at a constant air pressure are illustrated in figure. The performance of an air motor is dependant on the inlet pressure. At a constant inlet pressure, ungoverned air motors exhibit the characteristic linear output torque/speed relationship. Figure. [] de ahogo Potencia [] de arranque mín. Velocidad [] Figure Velocidad [] Figure However, by simply regulating the air supply, using the techniques of throttling or pressure regulation, the output of an air motor can be easily modified. The free speed and torque can be regulated down to 0% for an LZB air motor. The free speed for an LZL can be regulated down to % and the torque can be regulated down to %. The shaded areas in figure illustrate this. The use of gear units Air motors operate at high speed and, although they can be controlled over a wide speed range, the output characteristics are not always suitable for the application. To achieve the required output an appropriate gear unit can be selected. The ability to change the output by use of a gear unit is illustrated in figure. [0%] 0 [0%] 0 [] Potencia 0 0 : : : 0 0 LZB Velocidad [0%] 0 0 LZL Velocidad [0%] :, :, : = relaciones de engrane Velocidad [] Figure Figure The planetary and helical gear units used by Atlas Copco have a high level of efficiency that can be assumed to be 0%. The power output remains virtually unchanged also when gears are used. Note. The above does not apply to worm drive gear units, which can have high frictional losses and, therefore, loss of power output. AT L A S C O P C O A I R M O T O R S

8 Methods of modifying motor output Throttling A throttle is usually fitted into the motor s inlet hose, although it can also be fitted into the exhaust hose. When it is desirable to maintain a high starting torque but reduce running speed throttling is the best method of modifying the motor s output, Figure. [] [] Notes on performance data The performance data stated in this catalogue is valid for an air supply pressure of. bar (9 psi), gauge. Air consumption values are for free air delivery (ie, the volume the consumed air would occupy if allowed to expand to atmospheric pressure). The direction of rotation for a motor is always stated looking from the back of the motor. Figure 7 illustrate clockwise rotation. Velocidad [] Velocidad [] Figure Figure 7 Pressure regulation When using a pressure regulator it is mostly fitted into the motor s inlet hose. The use of pressure regulation is ideal when control of the stall torque is required and a high starting torque is not so important, Figure.

9 Introduction to Atlas Copco air motors and gear units LZB Vane motors 0. to.9 Type LZB Atlas Copco vane motors are compact in design, light in weight, and available with a host of different gear ratios to meet a variety of speed and torque requirements. They are particularly suited to be built into hand held machines, or indeed any industrial equipment. Planetary gear units Atlas Copco planetary gear units are particularly suited for use with LZB vane motors. The gear and motor components can be accommodated within a single, extremely compact housing where they provide high torque capacity for their size and exceptional efficiency, Figure. Stainless steel air motors Atlas Copco s stainless steel motors enlarge the field of applications to areas where the environment is corrosive. This can be in the food processing industries where corroding detergents are used or in the chemical industry where the atmosphere as such is corrosive. Atlas Copco s stainless steel motors have a clean design. Their smooth surfaces are cylindrical with no pockets where dirt can collect. The motors are easy to clean. The motors have double seals in Viton at the shaft end to prevent water from entering the gears. Explosion proof Our air motors are available in explosion proof certified versions, in compliance with the European Union.s ATEX Directive on equipment for potentially explosive environments. Figure Ex-Certified air motors are ideal in hazardous environments, where sparks or high outer temperatures might otherwise ignite explosive gases, vapour or dust.

10 Lubrication free air motors Atlas Copco s lubrication free air motors are equipped with low-friction vanes, sealed bearings and vented cylinder plates. Since they release no lubricants into the air, they offer a viable drive solution for sensitive processes and hygienic environments where oil contamination would be at best a problem and, at worst, a catastrophe. LZB high torque low speed air motors Accomplishing high torques generally calls for very large motors with correspondingly high air consumption. The LZB high torque/low speed air motors are based on the combination of LZB, the work horse in Atlas Copco s air motor program, and the gears used in the large LZB - motors. This gives a compact motor/gear package. The gears are dimensioned to stand being loaded at full stall torque indefinitely. Competing low speed air motors often have to limit their output torques to prevent gear breakage. LZB LR and LR low speed airmotors When there is a need for low speed only, the LR motors offer a complete and low price solution compared to the high torque LZB airmotors. Motors with brake The most popular vane motors, LZB, are available with parking brake. This brake is located between the motor and the gear. It is a disc brake that is spring activated when the motor is not running. When the motor is started the brake is released by a built in pneumatic piston. The brake is used when it is important that the output shaft must not turn when the motor isn t running and a torque is applied on the shaft. LZL Vane motors. to, Type LZL Atlas Copco vane motors have been designed to offer outstanding starting and low speed performance. These general purpose motors are powerful, rugged and hard wearing, Figure. Helical gear units Atlas Copco helical gear units are normally fitted to Type LZL vane motors. Standard units are highly efficient, providing speeds of 00 down to at torques of up to 00. The gear unit is flange-coupled to the motor and the shafts are joined by a flexible coupling, Figure Worm gear units Figure Figure The LZL vane motors can also be supplied with worm gear units. In this configuration, they will deliver speeds of 00 r/ min down to at torques of up to 70. Worm gear units have a self-braking action that can be beneficial in certain applications. The worm gear unit is flange-coupled to the motor and the shafts are linked by a flexible coupling, Figure.

13 LZB Vane motors Introduction LZB vane motors are designed to provide high performance and high standards of reliability. Typically, they are characterized by a high power output and small physical size, Figure. Fr (N) Figure Curve e Curve g 000 Fa (N) The design of the motor is chosen to be long and slim. This gives a number of advantages like a high power to volume ratio, a low air consumption and long vane life. All motors utilise five vanes, which are supplied with vane air, to ensure excellent starting and low speed performance. Multi-step planetary gears are used to meet the torque and speed requirements of the application, offering high efficiency with compact dimensions. Cylindric shaft Fr A Fa Figure Threa shaft Shaft loading The maximum allowable loads on a given motor s output shaft are illustrated in Figure. The relevant load curve code for a motor is stated in the data tables for each specific motor designation, under the Shaft load code column. These values have been calculated for shaft and bearing working lives of million turns. To achieve a working life of 0 million turns, the loading factor must be halved.

14 Mounting Type LZB vane motors may be mounted in any position. To facilitate this, flange and foot mounting are available for each motor, Figure. Motor The compressed air supply should be connected to the inlet that gives the desired direction of rotation, Figure. The inlet not in use functions as an additional outlet: it must not be plugged. Foot Connection Flange Figure Non- Motor When the compressed air supply is connected to the inlet, the direction of rotation will be as shown in Figure 7. If the exhaust air is to be piped away, a hose should be connected to the exhaust outlet. (EXH). Certain models have a third outlet, which can be plugged without affecting the performance of the motor. Clockwise rotation Figure Hose dimensions Information on hose dimensions recommended for use with type LZB air motors is detailed in Table. These dimensions are valid for hose lengths up to m. If lengths above that are used, choose a one size larger hose. Anti-clockwise rotation Figure 7 Hose size up to m length.
