Question
Chapter 31, Problem 1RQ
To determine
Identify the number of slip rings on a rotor shaft of wound rotor motor.
Expert Solution & Answer
Explanation of Solution
One of the three major types of the three-phase motor is the wound rotor motor. The wound rotor motor is the first AC motor with speed control.
The wound rotor motors are also known as slip ring motors and have three slip rings on the rotor shaft.
Hence, there are three slip rings on a rotor shaft of a wound rotor motor.
