What component allows current to be supplied to an AC motor?

The component that allows current to be supplied to an AC motor is slip rings. Slip rings are crucial in enabling the transfer of electricity to the rotating part of an AC motor. Unlike brushes connected to a commutator used in DC motors, slip rings provide a continuous electrical connection as the motor spins. This ensures that the alternating current can be fed into the rotor without interruption, maintaining a steady operation of the motor.

In the context of an AC motor, slip rings facilitate the current supply by allowing the flow of electricity from stationary components to the rotating rotor, thus enabling the motor to function effectively. The design of slip rings helps in achieving a reliable connection as the rotor turns, making them essential for many types of AC motors.
