| Zusammenfassung: | To reduce AC loss (AC copper loss) which occurs in winding of a motor.SOLUTION: A motor has a stator and a rotor arranged with a gap with respect to the stator. The stator has an annular yoke, and a plurality of teeth projecting toward the rotor from an inner peripheral part of the yoke. A slot 53 is respectively formed between adjoining teeth, winding coil is arranged within the slot by a plurality of turns when the winding coil 60 including a plurality of single wires 60a is wound around the teeth, and the winding coil per turn is arranged in a radial direction or a circumferential direction within the slot.SELECTED DRAWING: Figure 2
【課題】モータの巻線で生じる交流損失（交流銅損）を低減する。【解決手段】モータは、ステータと、ステータに対して隙間を空けて配置されるロータとを備えるモータであって、ステータは、環状のヨークと、ヨークの内周部からロータに向かって突出する複数のティースとを有し、隣り合うティース間には、スロット５３がそれぞれ形成され、複数の素線６０ａを含む巻回用コイル６０がティースに巻回される際に、巻回用コイルが複数回のターンによりスロット内に配置され、ターンごとの巻回用コイルは、スロット内において径方向または周方向に配列される。【選択図】図２ |
