Asynchronous Motors ASM Overview General technical information Speed measurement An integrated rotary encoder from HEIDENHAIN measures the shaft speed. Motors with a solid shaft are fitted with an ERN1381 encoder with 124 lines. Motors with a hollow shaft are fitted with an ERM28 encoder with 6 lines. Specifications The specifications and the performance curves apply when motors are mounted without thermal insulation. All ratings apply with a maximum temperature rise of K on the winding based on 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 SEM asynchronous motors are fitted with maintenance-free s. The shaft s used on motors with solid shaft are available as either standard or high specification spindle s. When using spindle s the motor can withstand greater radial forces and allowing for higher spindle speeds. Motors with spindle are slightly longer. Hollow-shaft motors are always fitted with the high specification spindle s. Mechanical life The service life of the s depends on the shaft load and the average shaft speed (contact SEM for further details). The nominal 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 end 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 688-1. Feather key: ASM 2: A x 8 x 7 ASM 26: A2 x 8 x 9 ASM 32: A6 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 26 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 Dimensions IM B3 (for securing by flange/base) as per EN 6 34-7 Flange: Dimensions as per DIN 42 948 and IEC 72 Protection as per EN 6 29: IP 4 Vibration severity Grade SR (external precision balancing possible) (IEC 6 34-14) Thermal variables Separate cooling via integrated fan Temperature monitoring with KTY 84-13 thermistor in the stator winding Thermal class F 1
