What type of motor uses alternating current?

The induction motor is a widely used type of motor that operates specifically on alternating current (AC). It functions based on electromagnetic induction, which means that the current in the rotor is induced by the magnetic field created by the stator winding when AC is applied. This interaction between the magnetic field and the current in the rotor allows the motor to turn and perform work.

Induction motors are known for their robustness, simplicity, and efficiency, making them ideal for various applications in industrial and commercial settings. They do not require brushes or commutators as in DC motors, which contributes to their durability and lower maintenance needs. The design of the induction motor allows it to start easily and run smoothly on standard AC power supplies.

The other types of motors mentioned operate under different principles or power sources, which do not align with the function of the induction motor.
