STATOR OF ELECTRIC MOTOR, AND PERMANENT MAGNET TYPE ROTARY ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a stator in which a creepage distance can be assured and which is applicable to a small-size motor, and a permanent magnet type rotary electric machine.

SOLUTION: In a stator of an electric motor, having a yoke core and a plurality of teeth cores extending in the radial direction of the yoke core, a plurality of bobbins mounted on the teeth cores and formed of insulating material are provided. The bobbin consists of a body part around which an excitation winding of the stator is wound and flanges formed at both ends of the body part. Fitting parts for fitting the projection/recesses of the flanges of the adjacent bobbins one another to connect the plurality of bobbins to one another in the peripheral direction of the flanges are provided on end faces in the peripheral direction of the flanges on the inner diameter side of the flanges.
