AC Motors

Definition: AC motors convert alternating current into mechanical motion using electromagnetic induction.

Types:

• Induction Motor (Asynchronous): Most common; rotor lags behind stator field.
• Synchronous Motor: Rotor rotates in sync with supply frequency.
• Single-Phase: Used in household appliances.
• Three-Phase: High efficiency, used in industrial applications.

Key Components:

• Stator – stationary part with windings.
• Rotor – rotating part (squirrel cage or wound type).
• Enclosure – protects internal parts and provides cooling.

Applications:

Pumps, fans, compressors, conveyors, HVAC systems.
