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.
