Question
Chapter 44, Problem 1RQ
To determine
The number of slip rings on the shaft of wound rotor motor.
Expert Solution & Answer
Explanation of Solution
One of the most used type of motor is the wound rotor induction motor. It comes with wired range of speed control methods.
The wound rotor induction motor is also known as the slip ring induction motor as there are three rings on the shaft of the induction motor..
Thus, the three slip rings are on the shaft of wound rotor motor.
