The difference in operation between a stepping motor and the common DC motor.

Expert Solution & Answer
Check Mark

Explanation of Solution

Consider that the motor is the device that converts the electrical energy into the mechanical energy.

Stepping motor.

The stepping motor is operated in the open loop mode that is there is no feedback from the output to the input and the angular rotation of the motor depends upon the time of pulse.

DC Motors

Consider that DC motors are in the closed loop connection and the angular rotation of the rotor depends on the distance and the time and the position
