What is the principle of operation of a repulsion motor?

A repulsion motor operates on the principle of electromagnetic repulsion between the stator and rotor. When the stator is energized with alternating current, it creates a rotating magnetic field that induces current in the rotor. This induced current, in turn, generates its own magnetic field, which interacts with the stator's field, resulting in a repulsive force that causes the rotor to rotate. The motor typically requires a commutator to ensure that the rotor's magnetic field is properly aligned for continuous rotation.
