What is a Squirrel Cage Induction Motor?
A squirrel cage induction motor is a type of electric motor that operates using electromagnetic induction. It mainly consists of two essential parts: the stator and the rotor. The stator is the stationary part, while the rotor is the rotating part. The design resembles a squirrel cage, hence the name.
How Does It Work?
So, how does this motor actually function? Here’s a simplified explanation:
- Electric Current Input: When you connect the motor to an AC power supply, electric current flows into the stator windings.
- Magnetic Field Creation: This electric current generates a rotating magnetic field in the stator. It’s like magic!
- Induction of Current: The rotating magnetic field induces a current in the rotor bars. This happens because of electromagnetic induction, where a changing magnetic field creates an electric current in a conductor.
- Rotor Movement: The induced current creates its magnetic field in the rotor. Now, there is a magnetic interaction between the stator's rotating field and the rotor's magnetic field. This interaction causes the rotor to turn.
- Continuous Operation: As long as the motor is supplied with AC current, it keeps spinning. The rotor’s speed is slightly less than the speed of the magnetic field, which is known as slip. This is a crucial aspect of the motor's efficiency.
