20120086298 | MULTILAYERED WOUND COIL, STATOR, AND MANUFACUTING METHOD THEREFOR - Disclosed are a multilayered wound coil, a stator, and a manufacturing method therefor. The stator is provided with: a stator core comprising laminated steel sheets; and a coil which is wound around a teeth section formed on the stator core and has a plurality of layers formed in the circumferential direction of the stator core. The winding of the coil proceeds in either the radial direction or the circumferential direction of the stator core, whichever direction has fewer adjacent conductors, and doubles back at the end in said direction. This reduces the difference in potential between adjacent conductors, making it possible to ensure insulation between adjacent conductors even with a thinner insulating film. | 04-12-2012 |

Each insulator has a shape including a pair of opposite side surface portions connected with an intermediate portion along a wall surface defining the slot. Each insulator includes end protrusions facing each other at free ends of the side surface portions to position the conductor segments. The insulators are made of an insulating and elastic material. | 10-11-2012 |
20140109392 | METHOD FOR MANUFACTURING ROTOR AND CLEAVING APPARATUS - In a method for manufacturing a rotor in which a plurality of cleaved magnet pieces are mounted in a rotor core with cleaved surfaces of the cleaved magnet pieces in an engaged state. In a cleaving step, a magnet workpiece having a recess in a surface thereof is cleaved at the recess as a starting point, thereby producing a first magnet piece and a second magnet piece. In a surface processing step, the cleaved surface is processed to reduce protrusions on the cleaved surface of the first magnet piece. Accordingly, the engagement between the cleaved surfaces is poor, the contact area is reduced, and the contact resistance is increased. As a result thereof, the eddy currents in the cut magnets flow less easily, and loss caused by eddy currents may be decreased. | 04-24-2014 |
