20100289374 | STATOR AND MANUFACTURING METHOD THEREOF - The disclosed embodiments relate to a stator and manufacturing method of the stator in which the coil conducts of the stator have three phases (a U phase, V phase, and W phase), which are arranged in a distributed winding form in a plurality of slots of a stator core. The coil conductors of the three phases each include a slot conductor portion that is disposed in the slot, and a pair of coil end conductor portions disposed on both axial sides of the stator core to connect the slot conductor portions disposed in the different slots. The stator also includes a first side transition wire portion in each phase that is disposed further toward a radial inner side than an inner peripheral end surface of a tooth provided on each circumferential side of the slot so as to overlap another first side transition wire portions in the axial direction. | 11-18-2010 |
20120019085 | ROTARY ELECTRIC MACHINE ARMATURE - A rotary electric machine armature that can be produced by a simplified manufacturing process and at a reduced manufacturing cost. The armature core includes a plurality of slots extending in the axial direction of a cylindrical core reference surface and are distributed in the circumferential direction of the core reference surface and a coil wound in the armature core. The coil is formed by joining a plurality of segment conductors to each other; each of the segment conductors includes a straight conductor side portion disposed in the slot, a parallel projecting portion extending in parallel with an extension direction of the conductor side portion to project in the axial direction from the armature core, and an oblique projecting portion provided opposite the parallel projecting portion in the axial direction and extending from the conductor side portion to project in the axial direction from the armature core. | 01-26-2012 |
20120228984 | ARMATURE FOR ROTATING ELECTRIC MACHINE - In an armature, a coil includes a plurality of conductor segments, each provided with a conducting side section and a pair of protruding sections.
