摘要： The invention relates to a multipole commutator motor (14) having at least four stator poles (16-19) and having armature coils (31-42) that work together with these stator poles and that, for the supply of power, are each connected electrically with two commutator bars (1-12) of a commutator (22), and whose number is greater than the number of the stator poles (16-19), it being provided that, in order to reduce the number of brushes (20, 21; 23, 24) contacting the commutator (22), armature coils (31-42), that form armature poles having identical magnetic orientation are connected in parallel through electrical bridge conductors (43-48) at the armature. For the commutator motor (14), it is proposed that the bridge conductors (43-48) be routed at least partially via armature slots (71-82).

摘要： The present invention provides a dynamo-electric machine that suppresses vibrations caused by imbalance due to electromagnetic forces and that also suppresses imbalance in magnetic attraction forces generated owing to the difference in the number of coil portions among electric circuit portions. This dynamo-electric machine comprises an armature having a winding consisting of a plurality of coil portions each formed by lap-winding a conductor between a corresponding pair of slots formed in an outer circumferential surface portion of a core fixed to a shaft in such a way as to extend in an axial direction thereof, a commutator fixed to an end portion of the shaft and having a plurality of segments to which both end sections of said coil portions are electrically connected, brushes made to respectively abut against the surfaces of the segments of the commutator, and equalizers for connecting said segments, which are to be at equal electric potential, to each other. Moreover, the coil portions are parallel-connected to one another between the segments, and disposed in such a manner as to be symmetrical with respect to a mechanical angle of 360 degrees.
