Abstract
An electric rotary machine comprises a cylindrical pole tooth ring and a plurality of salient poles each including a pole tooth. The salient poles are each positioned and fixed such the pole tooth makes firm contact with the pole tooth ring by means of each of a plurality of mechanisms, which are arrayed circumferentially on the pole tooth ring, and which each comprise bend-ups adapted to be elastically deformed when the pole tooth is fitted into the mechanism.
Claims4
