Asynchronous Motors General technical information Speed measurement An integrated rotary encoder from HEIDENHAIN measures the shaft speed. • Motors with solid shaft are fitted with an ERN 1381 encoder with 1 024 lines. • Motors with a hollow shaft and the ASM ERM 280 encoder with 600 lines. curves apply when motors are mounted without thermal insulation. All ratings are based on a maximum temperature rise of 105 K on the winding with a maximum am- bient temperature of 40 °C. If the motor is mounted so that it is thermally insulated, it is necessary to reduce the motor torque in order to...
