Patent ID: 8922090

Claim:
A rotating electrical machine including a plurality of magnetic poles installed on a circumference and an armature provided oppositely to inner peripheries of the magnetic poles, the armature comprising a shaft, an iron core fixed to the shaft and having a plurality of slots extending in an axial direction, an armature winding inserted into the slots, a commutator provided fixedly to the shaft on a front side of the iron core and having a plurality of commutator segments arrayed in a rotating direction of the shaft, and an equalizer electrically connecting the commutator segments that are configured to have a same potential using conductive wires folded back by passing through the slots, the rotating electrical machine being characterized in that: the equalizer connected at one end to a commutator segment among the commutator segments at a position at which the commutator segment is in contact with a first brush reaches a back side of the iron core by passing through a slot positioned at a center of one of the magnetic poles and returns to the front side by passing through a slot positioned at a center of another of the magnetic poles so that the equalizer is connected at the other end to another commutator segment among the commutator segments at a position at which the other commutator segment is in contact with a second brush of a same polarity as the first brush.
