The stator is an unmoving component of an electrical machine that’s going around the rotor. It’s derived from the word ‘’stationary’’ as the ‘’stator’’ implies. It contains the windings and provides mechanical support and protection for the motor.
The stator of an induction machine
The rotor is a general term for the main spinning part of an electrical machine and derived from the word ‘’rotating’’. Sometimes ‘’shaft’’ and ‘’armature’’ are alternatively used too. It’s the part of the machine on which electromechanical energy conversion occurs.
