にできる。As explained above, this invention is formed by fitting an outer ring yoke part forming an outer ring part and an inner ring magnetic pole part disposed within the outer ring yoke part and having slots and connecting a plurality of magnetic pole pieces. a stator core, an insulating part that covers the inner magnetic pole part of the stator core, and a first rotating shaft that is molded integrally with the insulating part and covers one end face of the inner magnetic pole part and communicates with the end face of the inner magnetic pole part. An insulating resin formed in a funnel shape with a through hole and a winding frame column having a bottle integrated with the insulating resin and projecting on the magnetic pole piece are provided, and a rotor is inserted into the inner ring magnetic pole part. A funnel-shaped insulating cover having a second rotary shaft through hole communicating with the first rotary shaft through hole is attached to the other end surface of the inner ring magnetic pole piece, and the end of the coil is hung in the bin. In the stator formed by winding the coil in a protruding manner between the slots, coil grooves are provided between the insulating resin and the winding frame pillars and between the insulating cover and the winding frame pillars,
The coil is placed inside the coil groove, which increases the area occupied during winding.Furthermore, the coil can be wound parallel to the end face of the internal magnetic pole part so that it has a flat shape, so the outer circumference of the coil end becomes smaller and the coil end becomes smaller. The length can be reduced and the electric motor can be made smaller.
