Detailed explanation-1: -ROTOR-The rotating part of an electrical machine such as a generator, motor, or alternator. SELF-INDUCTION-Voltage which occurs in a coil when there is a change of current.

Detailed explanation-2: -With this simple understanding, we can divide any motor into two physical parts; one part which rotates-called the rotor-and one part which doesn’t-called the stator. Figure 1 shows a simple diagram of an electrical machine showing the rotor and stator.

Detailed explanation-3: -commutator in Electrical Engineering A commutator is the metal cylinder on the armature shaft of an electric motor, that is used to make electrical contact with the rotating coils and ensure that the current flows in one direction.

Detailed explanation-4: -The armature is mounted on bearings and is free to rotate. It is mounted in the magnetic field produced by permanent magnets or current passing through coils of wire, which are called the field coils. When a current passes through the armature coil, forces act on the coil and result in rotation.

Detailed explanation-5: -As current flows, the coil generates torque that interacts with the original magnetic field, and then the coil starts rotating.
