A varnish impregnation apparatus that includes a support that supports a stator, in which the stator coil is mounted to the stator core, with an axial direction of the stator directed in a horizontal direction while grasping a radially outer side of the stator, and that is rotationally driven by a rotary device to rotate the stator; a varnish dropping device that drops the varnish toward a coil end portion of the stator which is rotated while being supported by the support; and a heater disposed in a cavity portion provided at an axial center of the stator core of the stator supported by the support to heat the stator from a radially inner side of the stator.

Varnish impregnation apparatus and varnish impregnation method

A method for manufacturing a stator for a rotating electrical machine by placing coils in a stator core, wherein each of a plurality of teeth formed in a radial pattern in an inner periphery of an annular yoke portion in the stator core has tip-end parallel side surfaces formed in its tip end portion having a constant width in a circumferential direction, has intermediate tilted side surfaces continuous with the tip-end parallel side surfaces and formed in its portion whose width in the circumferential direction increases closer to an outer periphery, and has base-end parallel side surfaces continuous with the intermediate tilted side surfaces and formed in its base end portion having a constant width in the circumferential direction.

Method for manufacturing a stator for a rotating electrical machine

A manufacturing method of a stator for manufacturing a stator by mounting a concentrated winding coil wound with a square wire conductor on each of a plurality of teeth in a stator core and welding end of the concentrated winding coil to corresponding end of another concentrated winding coil, characterized in that a first set of concentrated winding coils and a second set of concentrated winding coils are mounted on the teeth, and the welding of each end in the first set of concentrated winding coils and corresponding end in the second set of concentrated winding coils is started while a third set of concentrated winding coils is mounted on the teeth.

Manufacturing method of a stator

A manufacturing method for an electric motor rotor includes: a stacking process in which a plurality of iron core pieces are stacked to form a laminated iron core; a magnet insertion process in which a permanent magnet is inserted into a magnet insertion hole provided in the laminated iron core; a resin filling process in which the laminated iron core is heated to fill the magnet insertion hole with a molten resin for magnet fixation; and a rotary shaft assembly process in which a rotary shaft is warm-fitted into a rotary shaft insertion hole of the laminated iron core utilizing residual heat from the heating of the laminated iron corein the resin filling process.

Manufacturing method for electric motor rotor

A resin filling device for a laminated iron core, the resin filling device being used when a magnet insertion hole provided in the laminated iron core of a rotor for an electric motor is filled with a molten resin for fixing a magnet. The resin filing device configured with a resin feeding mold, an opposing mold, and a pressing mechanism that applies a compression force with the laminated iron core sandwiched between the resin feeding mold and the opposing mold. The resin feeding mold includes one or more discharge outlets arranged so as to face the opening of the magnet insertion hole, and configured to include a diameter reducing part in which an inner diameter is reduced gradually along a discharge direction of the molten resin. A diameter reducing part is arranged inside of the laminated iron core.

Resin filling device

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.

Three-phase motor

An automobile comprises a carrier lock device associated with the spare tire carrier, a striker associated with a back door and engaged by the carrier lock device, and a carrier lock reinforcement supporting the striker firmly and fixed to the back door. The carrier lock reinforcement is secured to the inner panel part constituting the lower side part of the back door, and the carrier striker fixed to the reinforcement is passed through the outer panel of the back door and projects backwardly.
