摘要： A stator includes a hollow cylindrical stator core having stator teeth and slots. The stator teeth each extend radially inward and are circumferentially spaced from one another. Each of the slots is formed between one circumferentially-facing pair of the stator teeth and opens at the radially inner periphery of the stator core. Each of the stator teeth has a distal end portion that includes a slit, a base part and an oblique part. The slit is formed in a distal end surface of the stator tooth and extends axially. The base part and the oblique part are formed respectively on opposite circumferential sides of the slit. The base part extends radially inward to have a distal end surface that makes up an inner-diameter surface of the stator core. The oblique part is bent toward an adjacent slot so as to extend obliquely with respect to the base part.

摘要： A ring manufacturing method and a ring manufacturing apparatus according to the invention does not require the preparation of a specially shaped plate material for each type of ring plate to be manufactured. It is therefore possible to manufacture a ring plate of any thickness or width with a high degree of accuracy even in high-variety, low-volume production. In a plate material forming step, a round bar 1 is formed by rollers 3, 4 into a plate material having any desired cross-sectional shape. In a slant rolling step, the plate material is slant rolled by slant rollers 9, 10 and thereby formed into a specially shaped plate material whose thickness increases in the width direction from one side to the other. In a ring forming step, this specially shaped plate material is formed into a ring shape by a ring forming device 14. The specially shaped plate material can be formed on the ring forming production line, whereby the accuracy of the shape of the resulting ring is achieved without having to separately prepare a specially shaped plate material for each type of ring plate to be manufactured.

摘要： The electric rotating machine includes a stator winding constituted of conductor segments each having a pair of in-slot portions and a coil end section projecting from both axial ends of a stator core. The coil end section includes a joint-side end portion having a skew portion intersecting with another one of the conductor segments at an axial end of the stator core. The skew portion is formed with a joint end portion at an extremity thereof, the joint end portion being formed with a conductor exposed portion where an inner conductor is exposed and joined to a conductor exposed portion of another conductor segment. A joint area between the joint end portions and a vicinity thereof are covered by an insulating resin member. The insulating resin member is thicker at a portion covering the conductor exposed portions than at a portion covering other than the conductor exposed portions.
