An electric rotary machine includes a stator comprising: a stator ring; a plurality of discrete salient poles each comprising a bobbin with guide grooves and a pole tooth with a groove, disposed inside the stator ring, and fixed by a molding resin injected inside the stator ring; and a positioning ring having protrusions at its outer circumference and engaging with the discrete salient poles such that the protrusions are each fitted into the groove of the pole tooth.

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.

A two-phase unipolar driving brushless DC motor of a radial gap type having a rotor position detector (100) includes a main-pole yoke (17) having main-poles (17A), an interpole yoke (13) coaxially provided with the main-pole yoke (17) in a superposed manner and having interpoles (13A) and an axial short-circuit portion or member (14) provided in an axially extending portion in magnetic fluxes (F) formed in the main-poles (17A) and interpoles (13A). This structure allows for easy winding of coils (15) around the main-poles (17A) and enhanced winding space factor in order to increase the starting torque and to improve the motor efficiency.
