A motor includes a rotation shaft, a stator, and a rotor. The stator includes an armature winding and a stator core including a main core portion with an axial stack of core sheets and a magnetic plate on an end thereof. Each core sheet includes a tooth formation portion around which the armature winding is wound. The magnetic plate includes a stacked portion and an axially extending portion. The stacked portion stacked on the axial end of the main core portion and includes an end located toward the rotor. The axially extending portion extends toward the outer side in the axial direction from the end of the stacked portion located toward the rotor and is opposed to the rotor in a radial direction of the motor. The axially extending portion is shaped to be magnetically skewed in a circumferential direction relative to the tooth formation portion and the stacked portion.

Motor, method for manufacturing magnetic plate, and method for manufacturing stator

A method for manufacturing a stator configured to ensure insulation properties between a conductor and an armature core while preventing a manufacturing cost from increasing and preventing a space factor from lowering. In an edge-removing step, a plurality of independent edge-removing punches, which correspond to one slot S or two or more slots S, press and chamfer a corner portion of an axial opening edge of the slot in an axial end core sheet of the armature core.

Method for manufacturing an armature core

A stator includes a core having a plurality of slots and a plurality of U-shaped conductors, which are inserted in the corresponding slots. Each of the conductors has a pair of legs and a joint portion that connects the legs together. Each slot receives four legs and each of the legs in the slot is one leg of the corresponding one of the conductors. Two of the four conductors corresponding to the four legs inserted in each slot are overlapped with each other at the joint portions as viewed at least circumferentially.

Stator having conductors that are overlapped with each other at joint portions in a circumferential direction, motor having the stator, method for manufacturing the conductors and method for manufacturing the stator

An armature core of a stator has an annular portion and a plurality of teeth extending radially from the annular portion. A segment coil is configured by electrically connecting a plurality of segment conductors together. The segment conductors extend axially through slots S, each of which is defined between each adjacent pair of the teeth. Each of the teeth has a width adjustment portion for decreasing a slot width in a direction perpendicular to a radial direction in the radially inward direction.

Stator and motor

A special terminal may project from an encapsulation body of a semiconductor module and may be engaged with an engaging portion of a motor case to limit a positional deviation of the semiconductor module relative to the motor case. Additionally or alternatively, a module side engaging portion may be formed in the encapsulation body and may be engaged with a case side engaging portion to position the semiconductor module relative to the motor case.
