  • Patent number: 9214847
    Abstract: Provided is a motor comprising: a stator equipped with a coil basket, which is a distributed winding coil that uses flat wire, and a stator core; and a rotor with a central shaft. The motor is characterized in that: the coil end at one end of the coil basket has bent sections that are bent on the rotor side in relation to wire sections inside slots of the stator core; and a lower-side concentric section and horizontal sections, which comprise the coil end at the other end, are positioned further toward the shaft center side of the rotor than the inner peripheral surface of the teeth; and the coil end at one end and the coil end at the other end comprise five flat wires that are lap wound in a flatwise direction.

  • Patent number: 8884489
    Abstract: A flat conductor wire in a U-phase first slot of a first group block and a flat conductor wire in a U-phase second slot of a second group block form an outer circumference base unit. A flat conductor wire in a U-phase second slot of the first group block and a flat conductor wire in the U-phase first slot of the second group block form an inner circumference base unit. The inner circumference base unit is located inside the outer circumference base unit. A coil end portion at one end of the inner circumference base unit and a coil end portion side at one end of the outer circumference base unit are bent toward the rotor side with respect to an in-slot conductor portion in the stator core. The coil end portion side at one end of the inner circumference base unit and the coil end portion side at one end of the outer circumference base unit are located further toward the axis of the rotor than an inner peripheral surface of the stator core.

  • Publication number: 20130049515
    Abstract: A stator includes a stator core, a stator winding, and insulation paper sheets. The stator winding is constructed by forming a Y connection of phase windings each of which is constructed by inserting conductor segments into slots from a lower end side of the stator core and joining distal end portions of the conductor segments which protrude from an upper end side of the stator core. One of the insulation paper sheets is disposed between radially adjacent ones of joint portions that constitute a group of joint portions in a U-phase winding that are the nearest to a U-phase terminal. In the same manner, the other insulation paper sheets are disposed with respect to a V-phase winding and a W-phase winding. Surfaces of the other joint portions are covered with an insulation resin. Insulation paper sheets are disposed between joint portions that need long creepage distances and the insulation resin is used to cover surfaces of the other joint portions that do not need a long creepage distance.

  • Patent number: 8215260
    Abstract: A rotary electric machine-manufacturing apparatus utilized to implement a process of infiltrating varnish into wire-wound coils of a rotary electric machine, and of curing the varnish, an apparatus includes a rotator 2 supporting a work S attached with the wire-wound coils Sc and rotating the work; and a high-frequency power supply device supplying electric power to the wire-wound coils. It is thus possible to support and heat up the work without having devices that surround the work S, thereby positioning a varnish dropping-infiltrating device 6 appropriately. Further, there is no need to change a stage as conventional heat-up processes with an oven or a hot blast-circulating furnace did, and an entire process from pre-drying to curing can be implemented at a single stage.

  • Patent number: 7064470
    Abstract: A three-phase motor having a stator in which the dimensions of protrusion of coil end parts in winding coils of individual phases can be equalized as much as possible and in which the overall dimension of protrusion of the coil end parts in the winding coils of the three phases can be reduced to an optimal dimension is provided. Each of unipolar coils forming the winding coils of the three phases has a pair of coil end parts protruding from end parts in the axial direction of a stator core. The winding coils of the three phases have the relationships of Cv/Cu=0.88 to 0.98 and Cw/Cv=0.88 to 0.98, where Cu, Cv, Cw represent average lengths of electric wires forming the coil end parts in the three phases of U-phase, V-phase and W-phase.
