AC Geared Servo Motor is permanent split capacitor induction motor, no brushes or starting is employed. The Motor has the feature that in normal mode of operation a fixed voltage is impressed on the reference phase and a variable voltage, in quadrature to reference voltage is given to the control phase. The Motor is offered in compact size, low output speed and quick reversibility. The AC Geared Servo Motor has good starting torque, easy speed control and has ability to withstand for continuous stalled rotor condition.
