Abstract
An electric motor stator has a stator core and a plurality of windings wound around teeth of the stator core. Each of the windings has two tooth winding portions with a crossover wire extending therebetween. Each of the windings starts from a neutral wire and winds around a first tooth to form a first tooth winding portion and then winds around an opposed tooth to form a second tooth winding portion with the crossover wire extending as a power wire. Thus, the second tooth winding portion is started from the power wire. A terminal end of the second tooth winding portion is drawn out and connected to the neutral wire. The stator core has an insulator having support portions for preventing the tooth winding portions from falling outwards. The power wire is held between the tooth winding portion and a slot bottom so as to be fixed.
