Abstract
An electric rotary machine is provided, in which a stator armature includes a stator ring that encloses a plurality of salient poles each with a pole tooth thereby forming a magnetic circuit, and in which the inner surface of the stator ring is made flat at portions to be in contact with the outer end faces of the pole teeth so that the stator ring can make surface-to-surface contact with the pole teeth without any air gap therebetween so as to secure a well-balanced magnetic circuit.
