Zusammenfassung:PROBLEM TO BE SOLVED: To provide a motor having enhanced occupancy of a coil in a slot.SOLUTION: A stator core 10 includes an annular yoke 12 and a plurality of teeth 14 protruding from the annular yoke 12 to the radial inner circumferential side. A plurality of slots are formed between each of the plurality of teeth 14. A plurality of racetrack coils 30 respectively include windings 32 which are regularly aligned and wound. The plurality of racetrack coils 30 are respectively housed in the plurality of slots with the maintained regular alignment of the windings, in the form of distributed winding in which one side of an outer circumference and one side of an inner circumference are inserted into different slots.SELECTED DRAWING: Figure 4 【課題】スロット内のコイルの占有率を高めたモータを提供する。【解決手段】ステータコア10は、円環状ヨーク12および円環状ヨーク12から径方向内周側に突起した複数のティース14を有し、複数のティース14の間に複数のスロットが形成される。複数のレーストラック型のコイル30は、それぞれが規則的に整列して巻回された巻線32を有する。複数のレーストラック型コイル30はそれぞれ、外周側の1辺と内周側の1辺とが異なるスロットに挿入される分布巻の形態で、巻線の規則的な整列を維持したまま複数のスロットに収容される。【選択図】図4
