5 New standards concerning efficiency published The IEC has introduced two new standards concerning energy efficient motors. IEC/EN -1 specifies new rules concerning efficiency testing methods, and IEC 30 defines new efficiency classes for motors. IEC/EN -1; 007 The new standard IEC/EN -1, which came into force September 007, introduces new rules concerning the testing methods to be used for determining losses and efficiency. It offers two ways of determining the efficiency; direct method and indirect method. The new standard specifies following parameters for determining the efficiency according to indirect method: reference temperature three options for determining additional losses: measurement, estimation and mathematical. Under the new standard ABB uses the indirect calculation method, additional losses determined from measuring. The resulting efficiency values differ from those obtained under the previous IEC testing standard, IEC : It must be noted that efficiency values are only comparable if they are measured using the same method. The motor documentation must state which method is used. The efficiency values on the technical data pages in this catalogue are given according to both new and old calculation methods. The table below shows the differences between old and new standard. Old efficiency testing standard EN/IEC : 1996 Direct method Indirect method: PLL (= additional losses) estimated at 0.5 % of input power at rated Winding losses in stator and rotor determined at 95 C. New efficiency testing standard IEC/EN -1: 007 Direct method Indirect method: Measurement; PLL calculated from tests Estimation; PLL at.5% - 1.0% of input power at rated between 0.1 kw and 1000 kw Mathematical calculation; Eh star - alternative indirect method with mathematical calculation of PLL Winding losses in stator and rotor determined at [5 C + actual temperature rise measured] IEC 30; 008 IEC 30: October 008 defines three IE (International Efficiency) efficiency classes of singlespeed, three phase, cage induction motors. IE1 = Standard efficiency (efficiency levels roughly equivalent to EFF in Europe nowadays) IE = High efficiency (efficiency levels roughly equivalent to EFF1 in Europe nowadays and identical to EPAct in USA for 60 Hz) IE3 = Premium efficiency (new efficiency class in Europe nowadays and identical to "NEMA Premium" in the USA for 60Hz) Efficiency levels defined in IEC 30 are based on tests methods specified in IEC -1: 007. Compared to old efficiency classes acc. to CEMEP agreement the scope been expanded. IEC 30 covers almost all motors (for example standard, hazardous area, marine, brake motors): Single-speed, three-phase, 50 Hz and 60 Hz, 4 or 6-pole Rated output from 0.75 to 375 kw Rated voltage UN up to 1000 V Duty type S1 (continuous duty) or S3 (intermittent periodic duty) with a rated cyclic duration factor of 80% or higher Capable of operating direct online Following motors are excluded from IEC 30: Motors made solely for converter operation Motors completely integrated into a machine (for example, pump, fan and compressor) that cannot be tested separately from the machine 1 ABB / LV Motors / Process performance motors EN

9 Insulation ABB uses class F insulation systems, which, with temperature rise B, is the most common requirement among industry today. The use of Class F insulation with Class B temperature rise gives ABB products a 5 C safety margin. This can be used to increase the ing for limited periods, to operate at higher ambient temperatures or altitudes, or with greater voltage and frequency tolerances. It can also be used to extend insulation life. For instance, a 10 K temperature reduction will extend the insulation life. Class F insulation system - Max ambient temperature 40 C - Max permissible temperature rise 105 K - Hotspot temperature margin + 10 K Class B rise - Max ambient temperature 40 C - Max permissible temperature rise 80 K - Hotspot temperature margin + 10 K Insulation system temperature class - Class F 155 C - Class B 130 C - Class H 180 C 1 Safety margins per insulation class M Surface treatment ABB Process performance motors are provided as standard with painting system that corresponds to corrosion category C3 M acc. to ISO/EN 1944:. C3 M means exterior urban and industrial atmospheres with moderate sulfur dioxide pollution and coastal areas with low salinity. Acc to ISO/EN 1944 the durability is divided into 3 ranges, low (L), medium (M) and high (H). Durability low (L) corresponds to -5 years, medium (M) to 5-15 years and high (H) more than 15 years. Other corrosion categories C4 M and C5 M are also available as option. Please see the variant code section. ABB / LV Motors / Process performance motors EN

10 Frequency converter drives for Process performance motors 1 Squirrel cage induction motors offer excellent availability, reliability and efficiency. With a frequency converter a variable speed drive (VSD) the motor will deliver even better value. A variable speed drive motor can be started softly with low starting current, and the speed can be controlled and steplessly adjusted to suit the application demand over a wide range. In addition, using a frequency converter together with a squirrel cage motor usually leads to significant energy and environmental savings. ABB s Process performance motors are designed for variable speed operation and especially with ABB Industrial Drives. There is a wide range of options available, making the motors suitable for even the most demanding applications. When selecting Process performance motors for variable speed drives, the following points shall be taken into consideration: 1. Dimensioning The voltage (or current) fed by the frequency converter is not purely sinusoidal. This may increase the losses, vibration, and noise of the motor. Furthermore, a change in the distribution of the losses may affect the temperature rises of the motor. In each case, the motor must be correctly sized according to the instructions supplied for the specific frequency converter. When using ABB converters, please use ABB s DriveSize program for the dimensioning. The tool utilizes dimensioning rules based on comprehensive combined type tests. For manual dimensioning, please note that the ability (or capacity) curves provided in this catalogue and in the respective manuals are indicative. Exact values specific to the motor and converter are available on request. In addition to thermal dimensioning, an adequate torque margin must be kept for stability. The maximum torque of the motor shall be at least 30% higher than the torque over the whole duty range. If long supply cables are used, the effect of these shall also be considered.. Operating speed Process performance motors are designed to operate over a wide speed range and in most cases also at significantly higher speeds than the nominal speed (i.e. the speed stamped on the rating plate). The maximum speeds can be found from the rating plates or from the DriveSize tool. In addition to the motor speed range, please ensure that the maximum or critical speed of the whole application is not exceeded. If a particularly low level of vibration is required, motors with improved balancing (variant code 417) shall be used. In high speed applications, the use of labyrinth seals (variant code 783) instead of V-rings shall be considered. Guideline maximum speed values for Process performance motors are shown in Table 1 below. Table 1. Guideline values of maximum speeds for Process performance cast iron motors Frame size Speed r/min -pole 4-pole SM, ML LK Ventilation At low speed operation the cooling capacity of the fan decreases, reducing the capacity of the motor. A separate constant speed fan can be used to increase cooling capacity and ability at low speeds. At high speeds, the use of metal fans (variant code 068) instead of plastic ones shall be considered. If a low noise level is required, the use of unidirectional or special low-noise fans is recommended. 4. Lubrication At variable speed applications, the bearing temperature varies as a function of speed and motor and the most accurate re-lubrication intervals can be achieved by measuring the bearing temperature under normal operating conditions. If the measured temperature is higher than +80 C, the re-lubrication intervals specified on the lubrication plate or in the motor manual must be shortened or lubricants suitable for high operating temperatures shall be used. See the ABB Low-voltage Motor Manual. With continuous operation at very low speeds as well as at very low temperatures, the lubrication capabilities of standard greases may not be sufficient and special greases with additives are needed. For more information, please contact ABB. If the motors are equipped with sealed bearings i.e. bearings greased for life, it must be noted that when the operating temperature differs from the design temperature, the lifetime of the bearing will also be 10 ABB / LV Motors / Process performance motors EN 1-008

11 different. More information about the lifetime of the bearings can be found from the product-specific sections of this catalogue and from the respective manuals. The use of so called conductive greases for elimination of bearing currents is not recommended due to their poor lubrication characteristics and low conductivity. 5. Winding insulation In order to ensure reliability of the motors, the effects of non-sinusoidal output voltages of the converters must be considered when selecting the correct insulation system and output filters for the converter. When using ABB s ACS800 and ACS550 drives with uncontrolled DC-voltage, the insulations and filters shall be selected according to Table below. For more information on du/dt-filters, please see the ABB Drives catalogues. If the instructions of the table are not applicable, and for other converters, the selection shall be based on the voltages present at the motor terminals: Table Nominal supply voltage UN of the converter UN 500 V The allowed phase-to-ground voltage peaks at motor terminals are: ABB Standard Insulation 1300 V peak ABB Special Insulation (variant code 405) 1800 V peak The maximum allowed phase-to-phase voltage peaks at the motor terminal as a function of the rise time of the pulse are shown in the graph below. The highest curve, ABB Special Insulation, applies to motors with a special winding insulation for frequency converter supply, variant code 405. The ABB Standard Insulation applies to motors with the standard design. 6. Bearing currents Bearing voltages and currents must be avoided in all motors to ensure reliable operation of whole application. Assuming the use of ABB ACS800 or ACS550 drives, with uncontrolled DC-voltage, insulated bearings and/or properly dimensioned filters at the converter must be used according to Table 3 below. For other alternatives and converter types, please contact ABB. When ordering, clearly state which alternative will be used. For more information about bearing currents and voltages, please see the Bearing currents in AC drive systems Fact File or contact ABB. Winding insulation and filters required ABB Standard insulation UN 600 V ABB Standard insulation + du/dt filters OR ABB Special insulation (variant code 405) UN 690 V ABB Special insulation (variant code 405) AND du/dt-filters at converter output UN 690 V AND cable length > 150 m ABB Special insulation (variant code 405) 1 DU/dt filters (reactor) Series reactor. DU/dt filters decrease the changing rate of the phase and main voltages and thus reduce voltage stresses in the windings. DU/dt filters also decrease so-called common mode currents and the risk of bearing currents. Insulated Bearings ABB uses bearings with insulated inner or outer races. Hybrid bearings, i.e. bearings with non-conductive ceramic rolling elements, can also be used in special applications. Common mode filters Common mode filters reduce common mode currents and thus decrease the risk of bearing currents. Common mode filters do not significantly affect the phase or main voltages on the motor terminals. For more information, please see ABB Drives catalogues.

12 1 7. Cabling, grounding and EMC The use of a frequency converter sets higher demands on the cabling and grounding of the drive system. The motor shall be cabled by using shielded symmetrical cables and cable glands providing 360 bonding (also called EMC glands). For motors up to 30 kw asymmetrical cables can be used, but shielded cables are always recommended, especially if there are sensitive components in the driven application. For motors in frame size IEC 80 and upward, additional potential equalization between the motor frame and the machinery is needed, unless they are installed on a common steel base. When a steel base is used for the potential equalization, the high frequency conductivity of this connection shall be checked. More information about grounding and cabling variable speed drives can be found from the manual Grounding and cabling of the drive system (Code: 3AFY R015 REV B) For fulfilling the EMC requirements, special EMC cable(s) must be used in addition to the correct cable gland mounting, with special, extra earthing pieces. Please refer to the manuals of the frequency converter. These guidelines present the maximum continuous torque of a motor as a function of frequency (speed) to give the same temperature rise as with rated sinusoidal supply at nominal frequency and full rated. The temperature rise of ABB s Process performance motors is normally class B. In such cases the dimensioning can be done according to the ability curve for temperature rise class B, or the motor can be slightly overed i.e. dimensioned according to the ability curve for temperature rise class F. However, if the ABB catalogue indicates that class F temperature rise is utilized on sinusoidal supply, the dimensioning shall be done according to the temperature rise class B ability curve. If the motor is utilized according to the ability curve for temperature rise class F, the temperature rise in other parts of the motor shall be noted and the lubrication intervals and type of grease checked. 8. Motor ability with ABB ACS800 and ACS550 drives The ability curves shown below are guideline curves. Please contact ABB for exact values. It is also possible to use the ability curve for other frequency converters, but it shall be noted that the harmonic content and control algorithms vary between different frequency converters, so the temperature rise of the motor will also differ.

20 Bearings The motors are normally fitted with single-row deep groove ball bearings as listed in the table below. If the bearing at the D-end is replaced with a roller bearing (NU- or NJ-), higher radial forces can be handled. Roller bearings are suitable for belt drive applications. When there are high axial forces, angular-contact ball bearings should be used. This option is available on request. When a motor with angular-contact ball bearings is ordered, the method of mounting and direction and magnitude of the axial force must be specified. For special bearings, please see the variant codes.

The inner ring is locked by tight tolerance to the shaft. All motors are equipped as standard with an axiallylocked bearing at the D-end. Transport locking Motors that have roller bearings or an angular contact ball bearing are fitted with a transport lock before despatch to prevent damage to the bearings during transport. In case of transport locked bearing, motor sizes 80 to 450 are provided with a warning sign. Locking may also be fitted in other cases where transport conditions are suspected of being potentially damaging. 0 ABB / LV Motors / Process performance motors EN 1-008

22 Bearing life The nominal life L 10h of a bearing is defined according to ISO 81 as the number of operating hours achieved or exceeded by 90% of identical bearings in a large test series under certain specified conditions. 50% of the bearings achieve at least five times this figure. The calculated bearing life L 10h for power transmission by means of a coupling (horizontal machine): Motor sizes 80 to ,000 hours. Lubrication On delivery, the motors are ready lubricated with high quality grease. The recommended grease used can be seen from ABB's Low Voltage Motors Manual delivered together with the motor or for frame sizes from the lubrication plate fastened to the motor frame. See example of a lubrication plate on page 4. Motors with permanently greased bearings Also motors with frame sizes can be equipped with permanently greased bearings. Bearings are lubricated with high quality, high temperature grease. Bearing types are mentioned in the rating plates. The following values can be used as a guide for bearing lifetime, depending on application and conditions: 4-8 pole motors about 40,000 h pole motors about 0,000 h Lubrication method in cast iron motors Regreasable bearings as standard solution Permanently greased bearings as an option Motors with relubrication nipples For sizes 80 to 450 the bearing system has been built so that a valve disc can be used to ease the lubrication. Motors are lubricated while running. Grease outlet opening has closing valves at both ends. This should be opened before greasing and closed 1- hours after regreasing. After lubrication close the valves. This ensures that the construction is tight and dust or dirt cannot get inside the bearing. As an option, a grease collection method can be used. Lubrication intervals ABB follows the L1-principle in defining lubrication interval. That means that 99% of the motors are sure to make the interval time. The lubrication intervals can also be calculated according to the L10-principle, which are normally doubled compared to L1-values. Values available from ABB at request.

23 Pulley diameter When the desired bearing life has been determined, the minimum permissible pulley diameter can be calculated using FR, as follows: D = K P n F R Permissible ings on shaft The tables give the permissible radial forces in Newtons, assuming zero axial force, ambient temperature of 5 C. The values are based on normal conditions at 50 Hz and calculated bearing lives for motor sizes 160 to 450 of 0,000 and 40,000 hours. Motors are foot-mounted IM B3 version with force directed sideways. In some cases the strength of the shaft affects the permissible forces. At 60 Hz the values must be reduced by 10%. For two-speed motors, the values must be based on the higher speed. Permissible s of simultaneous radial and axial forces will be supplied on request. where: D = diameter of pulley, mm P = power requirement, kw n = motor speed, r/min K = belt tension factor, dependent on belt type and type of duty. A common value for V-belts is.5. FR = permissible radial force If the radial force is applied between points X 0 and X max, the permissible force F R can be calculated from the following formula: F R = F X0 - X (F X0 - F Xmax ) E E = length of shaft extension in basic version M00001 Permissible radial forces Motor sizes 160 to 450 Length of shaft Ball bearings Roller bearings Motor extension size Poles E (mm) 0,000 hours F X0 (N) F Xmax (N) 40,000 hours F X0 (N) F Xmax (N) 0,000 hours F X0 (N) F Xmax (N) 40,000 hours F X0 (N) F Xmax (N) Frame sizes 71 to 13 on request 160 MLA MLB MLC MLD MLE MLA MLB MLC MLA MLB MLC MLD ABB / LV Motors / Process performance motors EN

25 Permissible axial forces The following tables give the permissible axial forces in Newton, assuming zero radial force, ambient temperature 5 C. The values are based on normal conditions at 50 Hz with standard bearings and calculated bearing lives of 0,000 and 40,000 hours. At 60 Hz the values are to be reduced by 10%. For twospeed motors, the values are to be based on the higher speed. The permissible s of simultaneous radial and axial forces will be supplied on request.
