摘要： A rotary electric machine configured with a stator, rotor, and permanent magnets disposed in an inverted V-shape that becomes gradually narrower from a side of a center of rotation of the rotor. The rotor is provided with a plurality of support portions that extend radially about the center of rotation, and gap portions are respectively formed in correspondence with the plurality of support portions at positions spaced by a predetermined distance from an edge portion of the permanent magnets in a flowing direction of magnetic flux between the permanent magnets and the stator. The gap portions are formed to have such a length that causes magnetic saturation during generation of low torque in a low-current state and that causes no magnetic saturation during generation of maximum torque in a high-current state in which electricity at a high current is supplied to the stator coil.

摘要： A method of welding a plurality of conductors to form a winding extending through an annular stator core. The conductors are inserted into slots formed in the stator core to have coil ends extending outside an end surface of the stator core. A plurality of pairs of the coil ends are arranged in diagonal arrays extending diagonally with respect to a radial direction of the stator core. The method inserts a first electrode into a gap between adjacent two of the diagonal arrays and then brings a second electrode close to one of the adjacent two of the diagonal arrays to arc-weld, the pairs of the coil ends. This welding method enables the welding of the coil ends arrayed in the above layout efficiently while keeping the electrical insulation between the pairs of the coil ends.

摘要： A stator includes an annular stator core and a stator coil. In each of slots of the stator core, there are received a predetermined number of in-slot portions of the stator coil in alignment with each other in a radial direction of the stator core. Each of side surfaces of tooth portions of the stator core includes, at its radially inner end, an oblique surface that extends obliquely with respect to the radial direction. The oblique surfaces are shaped so that for each of the slots, the circumferential width of the slot is decreased in the radially inward direction in that part of the slot which is located between a corresponding pair of the oblique surfaces. For each of the slots, the in-slot portion which is located radially innermost in the slot is held at a predetermined radial position by the corresponding pair of the oblique surfaces.
