STATOR

To provide a stator capable of improving reliability of insulation using an insulator.SOLUTION: A stator comprises: a split core 1A including a tooth part 11A around which a winding wire of a coil is wound, and a yoke part 11B which is formed while being expanded in an end of the tooth part 11A, and is disposed around a rotor including a rotary shaft; and an insulator 12 molded so as to cover at least a part of a surface of the tooth part 11A and at least a part of a surface of the yoke part 11B. Projected engagement parts 13 which are engaged with the insulator 12 are formed on a pair of side faces 11Aa directed toward adjacent split cores 1A on the surface of the tooth part 11A.SELECTED DRAWING: Figure 3 【課題】インシュレータによる絶縁信頼性を高めることが可能なステータを提供する。【解決手段】コイルの巻線が巻かれるティース部１１Ａおよびティース部１１Ａの端部に膨出形成されたヨーク部１１Ｂを持ち、回転軸を有するロータの周囲に配置される分割コア１Ａと、ティース部１１Ａの表面の少なくとも一部およびヨーク部１１Ｂの表面の少なくとも一部を覆うように成形されたインシュレータ１２と、を備え、ティース部１１Ａの表面のうち隣接する分割コア１Ａに向く一対の側面１１Ａａに、インシュレータ１２と係合する凸状の係合部１３が設けられている。【選択図】図３
