- The part in the middle with a coil of wire wrapped around a metal shaft is part of an electric motor. What is it?
- Rotor
⟹ The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.
⟹ The stator core, stator winding and the outer frame are the three parts of the stator whereas the rotor core and field winding are the parts of the rotor. The three-phase supply is given to the winding of the stator. The rotor is excited by the DC supply.
⟹ The rotor speed, rotational speed of the rotor, is usually measured in rotations per minute (rpm) or tip speed in feet per minute.
