What is Slip Ring Motor?
A slip ring motor is an AC motor in which the stator windings are connected to the rotor windings through slip rings. This type of motor is used for applications requiring high starting torque, such as cranes, elevators, and hoists. The slip ring motor is also known as a wound rotor motor.
What is Squirrel Cage Motor?
A squirrel cage motor is an AC motor in which the stator windings are connected to the rotor windings through a series of bars. This type of motor is used for applications requiring low starting torque, such as fans, pumps, and conveyors. The squirrel cage motor is also known as an induction motor.
Difference between Slip Ring Motor and Squirrel Cage Motor
- Starting Torque: Slip ring motors have higher starting torque than squirrel cage motors.
- Speed Control: Slip ring motors can be used for speed control, while squirrel cage motors cannot.
- Cost: Slip ring motors are more expensive than squirrel cage motors.
- Maintenance: Slip ring motors require more maintenance than squirrel cage motors.
