摘要： A permanent magnet type electric rotating machine comprises a stator (1) having a salient-pole concentrated winding, and a rotor disposed with a rotational gap (5), and having a plurality of permanent magnets (8) arranged and fixed in a circumferential direction inside, and an auxiliary salient pole (61) provided between the permanent magnets. A ratio of the number of poles for the rotor and the number of slots for the stator is 2:3 and, when a slot pitch of the stator is tau s (electrical angle), an angle &thetas; (electrical angle) made by a circumferential width of the permanent magnet in the surface of the stator side with an axis of the rotor is set at &thetas; ≒ n x tau s/2 + 8 x m (n=1 or 2, and m=1, 2 or 3). Thus, pulsation torque, cogging torque or the waveform distortion of a no-load induced voltage is selectively reduced as occasion demands.

摘要： A rotary electric machine having improved coil connection reliability, simplified coil end processing steps and improved workability based on an improved components mounting method is to be provided. Flat type conductors (201 - 208) are inserted in a stacked state into each of slots formed in a stator core, and a side face of a preceding-stage winding terminal end (22) and a side face of a succeeding-stage winding start end (23) in the flat type conductors are lapped and connected to constitute an assembly of stator coils. The stator coil assembly comprises plural coil groups, and one electrode is connected to one conductor end in the coil groups, while another electrode is moved in a successive manner to connect preceding- and succeeding-stage winding terminal and start ends of the conductors. Further, an insulating ring (61) with crossover conductors (37, 62, 63) laid thereon is combined with such stator coil assembly to connect winding terminal and start ends of the stator coil assembly, thereby constituting a predetermined winding circuit.
