Accepted Answer

Square cage induction motors have a squirrel cage rotor with bars and end rings made of copper or aluminum, while slip ring induction motors have a wound rotor with external resistors connected to slip rings.

Square cage induction motors have a simpler and more rugged construction compared to slip ring motors.
Slip ring induction motors allow for external resistance control, enabling speed control and high starting torque.
Square cage motors are more commonly used in applications where constant speed is required, while slip ring motors are used in applications requiring variable speed.
Square cage motors are more cost-effective and require less maintenance compared to slip ring motors.
