Rotating electrical machine and manufacturing method of the same

A manufacturing method of 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 equalizers electrically connecting the commutator segments that should have same potential using conductive wires folded back by passing through the slots, the manufacturing method being characterized in that:

• the equalizer is 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 brush, extended to a rear side of the iron core by passing through a slot positioned at a center of the magnetic pole, and returned to the front side bypassing through a slot positioned at a center line portion of another magnetic pole so that the equalizer is connected at the other end to a commutator segment at a position at which the commutator segment is in contact with a brush of a same polarity as the firstly-mentioned brush.
