Electrically, whether single-phase, 2-phase, or three-phase, the common AC _________ motor appears as a transformer to the applied electrical power.
The stator windings, which surround the pole faces of the stationary part of the electric motor, function as the primary of the transformer.
The rotor windings, whether several lengths of insulated wire wound in a specific pattern in a wire-wound rotor, or a cast of continuous conductors, such as aluminium, molded around the steel structure of the squirrel-cage rotor, serve as the primary of the transformer.
