Abstract
An electric rotary machine includes a stator comprising: a stator ring; a plurality of discrete salient poles each comprising a pole tooth, disposed inside the stator ring thereby forming a magnetic circuit, and fixed by a molding resin injected inside the stator ring; and a plurality of bobbins each constituting the salient pole, adapted to lodge the pole tooth fitted thereinto and to have a magnet wire wound thereon, and each including its outward-positioned flange having at its respective both ends two flexible thin-walled extensions which are adapted to securely hold the wound magnet wire in place, stay unbent during winding operation, and which are bent when the salient poles are put inside the stator ring.
