Question
Chapter 35, Problem 1RQ
To determine
The difference in operation between a stepping motor and the common DC motor.
Expert Solution & Answer
Explanation of Solution
Consider that the motor is the device that converts the electrical energy into the
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
