Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an electric motor capable of reducing a torque ripple while realizing multi-polarization and capable of reducing unpleasant noise.SOLUTION: An electric motor includes: a first coil 71 that is formed by winding a winding 73 between predetermined teeth 12 at N times in a forward direction; and a second coil 72 that is formed by winding the winding 73 between the predetermined teeth 12 to which the first coil 71 is formed at A times in the forward direction, and is formed by winding the winding 73 between other predetermined teeth 12 adjacent, forward in one direction, to the predetermined teeth 12 to which the first coil 71 is formed at N-A times in the reverse direction. A winding start end 73a of the winding 73 forming the first coil 71 and a winding starting end 73a of the winding 73 forming the second coil 72 are connected to a segment 15 of the same electric potential. A winding finish end 73b of the winding 73 forming the first coil 71 and a winding finish end 73b of the winding 73 forming the second coil 72 are connected to the segment 15 of the same electric potential.SELECTED DRAWING: Figure 3
【課題】多極化を図りつつトルクリップルを低減でき、不快音を低減できる電動モータを提供する。【解決手段】所定のティース12間に巻線73をN回、順方向に巻回して形成された第1コイル71と、第1コイル71が形成されている所定のティース12間に巻線73をA回、順方向に巻回すると共に、第1コイル71が形成されている所定のティース12間に一方向前方で隣り合う他の所定のティース12間に巻線73をN−A回、逆方向に巻回して形成された第2コイル72と、を有し、第1コイル71を形成する巻線73の巻き始め端73a、および第2コイル72を形成する巻線73の巻き始め端73aは、それぞれ同一電位のセグメント15に接続されていると共に、第1コイル71を形成する巻線73の巻き終わり端73b、および第2コイル72を形成する巻線73の巻き終わり端73bは、それぞれ同一電位のセグメント15に接続されている。【選択図】図3 |
