Electric Motor Stator

An electric motor stator, according to the present invention, comprises a stator core having a plurality of teeth and slots, each slot being formed between circumferentially adjacent teeth; and windings, a part of each winding being wound around teeth of the stator core. And, each winding includes tooth winding portions, a neutral wire, a crossover wire, and a power wire. The winding is wound around one of two opposed teeth, starting at an end of one tooth winding portion that follows the neutral wire, and the crossover wire directed from another end of the tooth winding portion around the one tooth toward the other of the opposed teeth connects to the power wire.

At an end of a tooth winding portion to be around the other tooth that continues from the power wire the winding is wound around the other tooth, and another end of the tooth winding portion around the other tooth is connected to the neutral wire. The electric motor stator further comprises an insulator having support portions that are placed at a bottom of the respective slots to prevent the tooth winding portions from falling radically outwards, and the power wire is held between the tooth winding portion and the insulator so as to be fixed.
