■ Features For  Reversible Motor

1.Reversible motor has a friction brake at the back of the motor body, which is designed for applications where reversal of direction is frequently required. For the friction brake the damp with spring impacts the rotating brake disk and supplies with continuous press.
2.The holding torque and overtravel of a simple brake will vary with the length of rotation time or temperature.
3.The reversible motor, like induction motor, is started by the capacitor and has a same torque characteristic with the induction motor.But the Reversible Motor is designed with a higher starting torque to increase the instant reversal features.
