The wound-rotor induction motor and the squirrel-cage induction motor both were developed for variable speed applications.

Question

Quizplus · Accepted Answer

The squirrel-cage induction motor is not typically developed for variable speed applications due to its design, which inherently provides a constant speed under load conditions. The wound-rotor induction motor, however, is designed with external resistors that can be adjusted to control the motor's speed, making it suitable for variable speed applications.
