  • Patent number: 12519362
    Abstract: An armature winding of multiple phases has a phase winding that is made of a plurality of partial windings for each phase. The partial winding includes a pair of intermediate conductor portions and crossover portions that connect the pair of intermediate conductor portions in an annular shape, and is configured by a conductor material being wound in multiple layers in the pair of intermediate conductor portions and the crossover portions. The intermediate conductor portions of the phases are arrayed in a predetermined order in the circumferential direction by one of the intermediate conductor portions of the pair of intermediate conductor portions of the partial winding of another phase being arranged between the pair of intermediate conductor portions of the partial winding. A sheet-shaped insulation covering body is provided in the intermediate conductor portion in a portion that opposes the intermediate conductor portion of the partial winding of another phase.

  • Patent number: 12519381
    Abstract: A rotating electric machine includes a multi-phase armature coil having phase windings each constituted of a plurality of partial windings, and a winding support member supporting the partial windings from a radially outer or radially inner side thereof. Each of the partial windings has a pair of intermediate conductor portions and a pair of bridging portions connecting the pair of intermediate conductor portions. All the intermediate conductor portions of the partial windings are arranged in alignment with each other in a circumferential direction. In each of the partial windings, insulating members are mounted respectively on the bridging portions of the partial winding. Brackets are provided respectively in corresponding ones of the insulating members of the partial windings in such a manner as to partially protrude from the corresponding insulating members. Protruding portions of the brackets, which protrude from the corresponding insulating members, are mechanically joined to the winding support member.

  • Patent number: 12009712
    Abstract: A rotating electric machine includes an armature coil having a plurality of phase windings for respective phases. Each of the phase windings is constituted of a plurality of partial windings each having a pair of intermediate conductor portions and a pair of bridging portions connecting the pair of intermediate conductor portions. All the intermediate conductor portions of the partial windings are arranged in a predetermined sequence in a circumferential direction. At each of coil ends of the armature coil, the bridging portions of the partial windings of different phases intersect one another. Each of the partial windings has a mounting member provided integrally therewith for mounting it to a support member. For each circumferentially-adjacent pair of the partial windings whose bridging portions intersect one another, the mounting members provided respectively integrally with the pair of the partial windings are together fixed to the support member by a common fixing member.

  • Patent number: 11984779
    Abstract: A rotating electric machine includes a field element having a plurality of magnetic poles of which polarities alternate in a circumferential direction, and an armature including an armature winding of multiple phases and an armature core having a circular cylindrical shape. The armature core is provided integrally with the armature winding. The field element and the armature are provided to oppose each other in a radial direction. An armature holding member includes a circular cylindrical portion assembled on an inner side in the radial direction of the armature core. The armature core and the circular cylindrical portion are fitted and fixed to each other with a predetermined tightening margin. A regulating portion regulates displacement in the circumferential direction of the armature core by engagement in the circumferential direction, and is provided in portions of the armature core and the circular cylindrical portion that oppose each other in the radial direction.
