Abstract:
An objective is to provide a motor stator that may achieve: a reduction in parts costs by shaping coil ends so that length thereof is reduced, thereby reducing the amount of use of copper, and minimizing the amount of use of binding strings for securing the coil ends in place; a reduction in manufacturing process costs by a structure which allows a protector and a wire lead outlet part to be easily assembled; and then an improvement in quality of a stator by firmly holding the coil ends and the protector. The motor stator may include a stator core 1 including slots; a plurality of cut surfaces forming flat surfaces on the outer surface of the stator core 1; end surface insulating plates 2 formed in an approximately same shape as the shape of magnetic steel plates punched out, and assembled into the stator core 1 on both axial end surfaces thereof; projections formed in a vicinity of a peripheral portion of an end surface insulating plate 2, and engaged with the cut surfaces on the stator core 1; slot-like cutouts, a little larger in size than the slots, formed on an inner peripheral side of the each end surface insulating plate 1; and coil ends. The coil ends are shaped by pressure against the end surface insulating plates 2.
