Abstract: A motor according to the present invention includes: a stator having a stator core and a coil; a rotor having a rotary shaft and a rotation body; a shaft bearing rotatably supporting the rotor; and a molding resin covering the stator. The motor has a coil end that is the coil protruding from the stator core in a shaft center X direction, and has a non-combustible layer provided to cover the coil end. The non-combustible layer is a metallic cover made of, for example, metal. The metallic cover is disposed to cover a periphery of a coil assembly in which the coil is formed on the stator core through an insulator. The metallic cover is integrated with the coil assembly by a molding resin.

Abstract: A molded motor of the present invention includes a rotor, a stator, a pair of shaft bearings, a pair of metal brackets, and a molding resin. The rotor has: a rotary shaft extending in a shaft direction; and a rotary body that has a permanent magnet and is fixed to the rotary shaft. The stator has: a stator core on which a plurality of salient poles are formed; and a plurality of coils each wound on each salient pole via an insulator, where the stator is covered by the molding resin and is disposed to face the rotor. The pair of metal brackets each fix each of the shaft bearings, and the shaft bearings rotatably support the rotor. Further, the rotary body has a dielectric layer formed between the rotary shaft and an outer peripheral surface of the rotary body. A metal member is provided, on an outer peripheral side of a coil end of the coil and on at least a part facing the coil end, in a circumferential direction.
