Features :
- Input pulse decides the rotation angle of the motor.
- High accuracy of around 3 to 5% a step.
- Provides good starting, stopping and reversing.
- Control of this motor is less costly because of exclusion of complex control circuitry.
- The speed is proportional to the frequency of the input pulses.
