An insulating resin formed in a funnel shape having a rotation shaft 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 attached to 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 part, and the terminal is connected to the bottle. In the stator in which a plurality of phases of coils are wound in a protruding manner between the slots, an insulating plate is provided between the phases of the coil, so that insulation between the coil phases is reliably ensured by the insulating plate. In addition, the coil is directly wound around the stator in a protruding manner, resulting in a shorter coil circumference, reducing the amount of coil used, and eliminating the need for a winding former, increasing the winding speed and reducing the height of the coil end. And since the coil no longer protrudes, post-processing can be eliminated.
