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.

Motor

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.

Molded motor

This motor has a stator formed by integrally molding a stator core, a stator winding wound around the stator core, and a grounding terminal mounted on the stator winding by insulating resin. The motor has a rotor provided with a shaft, a bracket mounting a bearing for supporting the shaft, and a conductive pin press fit in at least one hole having a predetermined diameter provided in the teeth of the stator core. The pin and the grounding terminal are electrically connected to each other.

Motor having a highly reliable grounding structure and electric equipment on which the motor is mounted

A motor comprises a stator having a stator core and a stator winding wound on the stator core and integrally molded with insulation resin, a rotor provided with a shaft, a first bearing and a second bearing for supporting the shaft, a bracket connected to the stator and retaining at least one of the first bearing and the second bearing, and a conductive member short-circuiting between the stator core and the bracket.

Motor and electric apparatus equipped with a conductive pin for suppressing electrolytic corrosion

A driving control apparatus consists of a battery for storing electric energy supplied to a motor-driven compressor and a drive motor, a direct current detector for detecting a direct current supplied from the battery to the compressor, a direct current voltage detector for detecting a d.c. voltage applied by the battery, a controller for calculating an electric power consumed by the motor-driven compressor, determining an upper limit of the electric power in dependence on the d.c. voltage, judging whether or not the electric power is larger than the upper limit, and controlling the compressor to reduce the electric power in cases where the electric power is larger than the upper limit. Because the upper limit of the electric power is determined in dependence on the d.c. voltage and because the electric power becomes necessarily lower than the upper limit, an electric tar is not stalled by the exhaustion of the electric power in the battery before a driver arrives at his destination. Also, air conditioning in the electric motorcar can be efficiently performed. Therefore, the driver and passengers can find pleasure in comfortable travelling.
