Abstract:
(EN) A stator comprising: an annular stator core continuing in the circumferential direction around a center shaft; a plurality of first teeth provided in part of the stator core in the axial direction and being arranged having intervals therebetween in the circumferential direction; a first umbrella provided at a radially inner end section of the first teeth; a plurality of second teeth provided at positions in the axial direction of the stator core that are different from the first teeth and being arranged having intervals therebetween in the circumferential direction; and a second umbrella provided at a radially inner end section of the second teeth. The first umbrella and the second umbrella have mutually differing width dimensions in the circumferential direction.
(FR) L’invention concerne un stator comprenant : un noyau de stator annulaire continuant dans la direction circonférentielle autour d’un arbre central ; une pluralité de premières dents disposées en partie dans le noyau de stator dans la direction axiale et étant agencées de manière à avoir des intervalles entre elles dans la direction circonférentielle ; un premier parapluie disposé à une section d’extrémité radialement intérieure des premières dents ; une pluralité de deuxièmes dents disposées à des positions dans la direction axiale du noyau de stator qui sont différentes de celles des premières dents et étant agencées de manière à avoir des intervalles entre elles dans la direction circonférentielle ; et un deuxième parapluie disposé à une section d’extrémité radialement intérieure des deuxièmes dents. Le premier parapluie et le deuxième parapluie ont des dimensions de largeur mutuellement différentes dans la direction circonférentielle.
(JA) 中心軸回りの周方向に連続する環状のステータコアと、ステータコアの軸方向の一部に設けられ、周方向に間隔をあけて配置された複数の第1のティースと、第1のティースの径方向内側の端部に設けられた第1のアンブレラと、ステータコアの軸方向において第1のティースとは異なる位置に設けられ、周方向に間隔をあけて配置された複数の第2のティースと、第2のティースの径方向内側の端部に設けられた第2のアンブレラと、を備え、第1のアンブレラと第2のアンブレラとは、周方向における幅寸法が互いに異なる、ステータ。
