What is the primary function of an AC motor?

The primary function of an AC motor is to transform AC electrical energy into mechanical energy. This process occurs because the alternating current supplied to the motor generates a rotating magnetic field within the motor. This magnetic field interacts with the motor's rotor, causing it to spin and produce mechanical motion. The ability to convert electrical energy from an AC source into useful mechanical work is essential in various applications, such as in appliances, fans, and machinery, making AC motors vital in industrial and residential settings.

The other options refer to different energy transformations that do not apply to AC motors. For instance, transforming mechanical energy into electrical energy pertains to generators, while transforming wind energy into electrical energy relates to wind turbines. Lastly, transforming chemical energy into mechanical energy typically concerns engines and batteries, not AC motors.
