Abstract

PURPOSE: To suppress the peak value of brushing sounds and to reduce the total brushing sound by providing uneven pitches for the lengths between the edges on the same side of commutator bars.
CONSTITUTION: Commutator bars 10 having the same configuration and the same dmensions are provided on the periphery of a commutator 9. Between the individual commutator bars, are inserted insulating bars 11 having different thickness. Pitch angles θ1∼θ5 for arranging the commutator bars 10 are uneven, and the pitches of lengths L1∼L5 between the neighbouring edges on the same side are also uneven. In this constitution, since the peak value of the noises generated when brushes 5 contact with the commutator bars 10 can be reduced compared with the noises generated by the commutator bars arranged at an equal pitch, the total brushing sound can be reduced.
