Title: MOLDED MOTOR
Abstract:
A molded motor according to the present invention is provided with a rotor, a stator, a pair of bearings, a pair of metal brackets, and a molded resin. The rotor has a rotating shaft extending in the axial direction and a rotating body that holds a permanent magnet and that is fixed to the rotating shaft. The stator: has a stator core in which a plurality of salient poles are formed, and a plurality of coils wound on the respective salient poles of the stator core with insulators interposed therebetween; is covered with the molded resin; and is disposed so as to face the rotor. The pair of metal brackets fix the respective bearings, and these bearings rotatably support the rotor. In addition, the rotating body has a dielectric layer formed between the rotating shaft and an outer circumferential surface of the rotating body. Furthermore, a metal member is provided in the circumferential direction at a site that is on the outer circumferential side of a coil end of the coils and that faces at least the coil end.
