Hysteresis Synchronous AC Gear Motor
- Model 730

Download PDF Version

A special characteristic of the hysteresis motor is a built-in clutch that disengages from the geartrain when power is removed. The clutch is important in applications that require resetting the geartrain. Re-energizing during reset will cause internal damage. Speeds available from 1/10 RPM to 15 RPM.

AC Gear Motor - Model 730 Features

  • Fully enclosed clutch is part of the gear train where it is protected from the external environment
  • When powered, clutch "locks in" and rotor drives through gear train to output shaft. On removal of power, clutch disengages rotor from gear train
  • Internal clutch operates as part of the motor, does not require a separate circuit
  • Motor operates in any mounting position
  • When de-energized, output shaft can be externally driven in the opposite direction from its operating direction of rotation
  • Mounting is compatible with other pear-shaped motors
  • Impedance protected
  • UL & CSA recognized
  • Options available...consult factory
