Is an induction motor AC or DC?

in Electrical Engineering

Is an induction motor AC or DC?

1 Answer

An induction motor is an AC motor. It operates on alternating current (AC) and works based on the principle of electromagnetic induction. The stator creates a rotating magnetic field, which induces a current in the rotor, causing it to rotate.

Induction motors are widely used in industrial and domestic applications due to their simplicity, reliability, and efficiency.
