ABSTRACT:
An electric motor with commutator having more than two poles comprises two brushes and two brush holders placed 90.degree. in relation to one another and mounted on an independent brush holder washer. To hold the washer centered during assembly, a pin 7 is provided, fastened to the washer approximately on the bisector of the angle formed by the two brushes, and in opposition to these brushes. Under the pressure of brushes 3, pin 7 rests along a generatrix of commutator 5 to stop washer 1 in a position almost centered in relation to the commutator, which then facilitates mounting of the flange constituting the cover and bearing of the electric motor.
