Zusammenfassung:PROBLEM TO BE SOLVED: To provide a resolver stator with a nobel structure.SOLUTION: A resolver stator 2 has an annular yoke 11, a stator core 7 having a plurality of tooth portions 12 protruding from the yoke 11 in a radial direction, an insulator 8 provided in the stator core 7, a plurality of coils 9 provided in each of the tooth portions 12 through the insulator 8, a plurality of connecting wires 10 connecting the coils 9 mutually, and a protection cover 5. The protection cover 5 has a protection cover body 50 covering and protecting the coils 9 and the connecting wires 10, and a plurality of weld-protrusions 52 protruding from the protection cover body 50 in a direction of a rotation axis. The insulator 8 has a plurality of weld-housing portions 19 respectively accepting the weld-protrusions 52. Each weld-housing portion 19 has a weld-bottom face 25A to which a weld-executing portion 57 of each weld-protrusion 52 is welded and an inner peripheral surface 26A surrounding each weld-protrusion 52.SELECTED DRAWING: Figure 7 【課題】新規な構造のレゾルバステータを提供する。【解決手段】レゾルバステータ2は、円環状のヨーク11と、ヨーク11から径方向に突出する複数のティース部12と、を有するステータコア7と、ステータコア7に設けられたインシュレータ8と、複数のティース部12の夫々にインシュレータ8を介して設けられた複数のコイル9と、複数のコイル9を相互に連結する複数の渡り線10と、保護カバー5と、を備える。保護カバー5は、複数のコイル9及び複数の渡り線10を覆って保護する保護カバー本体50と、回転軸方向で保護カバー本体50から突出する複数の溶着突起52と、を有する。インシュレータ8は、複数の溶着突起52をそれぞれ受け入れる複数の溶着収容部19を有する。各溶着収容部19は、各溶着突起52の溶着実行部57が溶着される溶着底面25Aと、各溶着突起52を取り囲む内周面26Aと、を有する。【選択図】図7
