rotor

An electric motor converts electrical energy into mechanical energy, typically through electromagnetic interactions. The rotor is a key component that revolves within a stationary part, known as the stator. In an induction motor, the rotor has conductors that interact with a rotating magnetic field produced by the stator windings. This interaction induces currents in the rotor, creating a torque that causes it to spin. The speed of the rotor is slightly less than the speed of the rotating magnetic field, a difference called slip. Some specialized motors, called wound-rotor induction motors, have insulated coils in the rotor connected to external resistors via slip rings, allowing for high starting torque and some speed control.123
