Asynchronous Motors ASM Overview General technical information Speed measurement An integrated rotary encoder from HEIDENHAIN measures the shaft speed. Motors with solid shaft are fitted with an ERN 81 encoder with 1 24 lines. Motors with a hollow shaft and the ASM 2M / rpm are fitted with an ERM 28 encoder with lines. Specifications The specifications and the performance curves apply when motors are mounted without thermal insulation. All ratings are based on a maximum temperature rise of 1 K on the winding with a maximum ambient temperature of 4 C. If the motor is mounted so that it is thermally insulated, it is necessary to reduce the motor torque in order to avoid thermal overloading of the motor. Shaft bearing SEM asynchronous motors are fitted with maintenance-free bearings. The shaft bearings used on motors with solid shaft are available as either standard or high specification spindle bearings. When using spindle bearings the motor can withstand greater radial forces allowing for higher spindle speeds. Motors with spindle bearings are slightly longer. Hollow-shaft motors are always fitted with high specification spindle bearings. Mechanical life The service life of the bearings depends on the shaft load and the average shaft speed (contact SEM for further details). The nominal bearing service life is 1, hours this depends on the specific motor, the maximum shaft load and the average motor shaft speed. Shaft end ASM asynchronous motors from SEM have a shaft extension as per DIN 748-1. The solid shaft motors have a centering hole as per DIN 332-DR. The standard versions of the asynchronous motor have a plain shaft (without keyway and feather key). Upon request the motors are available with keyway and feather key as per DIN 88-1. Feather key: ASM 2: A x 8 x 7 ASM 2: A2 x 8 x 9 ASM 32: A x 1 x 9 Precision balancing Balancing of ASM asynchronous motors from SEM can be done at any time. Hollow-shaft motors The ASM 2 UH and ASM 2 xh motors with hollow shaft are suited for direct mounting to mechanical spindles. The hollow shaft permits you to convey coolant to tools with inner cooling. The coolant is introduced at the rear of the motor through a rotating manifold (e.g. from Deublin, order no.: 119-2- 8). The shaft end is designed for this. Mechanical data Design IM B3 (mounting by flange/base) according to EN 34-7 Mounting of the motor We recommend using the following screws according to DIN EN ISO 417 to mount the motor: Fastening: Flange Base ASM 2 M12 x 3 M1 x 3 ASM 2 M1 x 4 M12 x 3 ASM 32 M x M14 x 4 Flange: Dimensions as per DIN 42 948 and IEC 72 Protection as per EN 29 Motor: IP 4 / Shaft end: IP 43 Vibration severity Grade SR (external precision balancing possible) (IEC 34-14) Thermal specifications Separate cooling via integrated fan Temperature monitoring with KTY 84- thermistor in the stator winding Thermal class F 1
