| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a motor capable of obtaining highly accurate detection results of a resolver.SOLUTION: In a motor, an annular portion 31 of a resolver stator core 32 having the annular portion 31 and teeth T1-T8 extending radially therefrom are fastened and fixed in the circumferential direction at a plurality of locations, for an end plate. The annular portion 31 is fastened and fixed by the holding portion 35c and the fixing piece 35d of a fixing plate 35, so that a local load is applied to the annular portion 31 at the circumferential positions corresponding to the all teeth T1, T3, T5, T7 around which any one of the sin wave output winding Ms or cos wave output winding Mc is wound.SELECTED DRAWING: Figure 2
【課題】レゾルバの高精度な検出結果を得ることができるモータを提供すること。【解決手段】モータは、環状部３１と環状部３１から径方向に延びるティースＴ１〜Ｔ８とを有するレゾルバステータコア３２の環状部３１が周方向に複数箇所でエンドプレートに対して軸方向に締結固定される。そして、ｓｉｎ波出力巻線Ｍｓ及びｃｏｓ波出力巻線Ｍｃのいずれか一方が巻回された全てのティースＴ１，Ｔ３，Ｔ５，Ｔ７と対応した周方向位置の環状部３１に局部的な荷重がかかるように環状部３１が固定プレート３５の挟持部３５ｃ及び固定片３５ｄとにより締結固定される。【選択図】図２ |
