  • Publication number: 20200028404
    Abstract: An electric motor includes: a stator that has a stator core and has coils that are formed of an electric wire wound on the stator core and form a plurality of phases; a resin covering the stator; and a wire break facilitator that facilitates the electric wire to break at a time of abnormality. In the electric motor having the stator in which the coils are covered with molding resin, the wire break facilitator is attached to at least one of: a transition wire part between the coils wound on the stator core; a connection part at a neutral point; and a connection part of a lead wire.

  • Publication number: 20200006991
    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.

  • Publication number: 20190372421
    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.

  • Patent number: 8269380
    Abstract: A brushless motor, to be used in a washing machine, includes a stator, a rotor, a magnetic sensor, and a drive circuit. The magnetic sensor and the drive circuit are accommodated in a case, and sealed with moisture-proof sealing resin, thereby forming a drive circuit unit, which is built in the brushless motor.
