する電動機。1. An outer ring yoke portion forming an outer ring portion, and a stator core formed by fitting an inner ring magnetic pole portion formed by connecting a plurality of magnetic pole pieces having slots to the outer ring yoke portion, The funnel has an insulating portion that covers the inner ring magnetic pole portion of the stator core, and a first rotary shaft through hole that is formed integrally with the insulating portion and covers one end surface of the inner ring magnetic pole portion and communicates with the center of the inner ring magnetic pole portion. -Shaped insulating resin and a winding frame pillar projecting on the magnetic pole piece integrally with the insulating resin and having pins are provided, and the rotor is inserted into the inner ring magnetic pole portion to perform the first rotation. A funnel-shaped insulating cover having a second rotary shaft through hole communicating with the shaft through hole was attached to the other end surface of the inner ring magnetic pole piece, and a coil whose end was twisted to the pin was formed between the slots. In a stator wound in a shape of a wire, Motor, characterized in that a drain hole.
