Abstract

PURPOSE:To absorb force applying to the brushes to eliminate the breakage of brushes and to equalize pressure of the brushes by a method wherein brush holder parts are supported with a body having elasticity, and the brush holders are made as movable freely in accordance with the motion of a rotor. CONSTITUTION:The brush holders 3 to hold the brushes 4 are fitted up to the bus ring 5, and the bus ring 5 is fixed to fixing parts 6 interposing springs 7 between them. Accordingly force being applied to the respective brushes 4 can be absorbed softly, and the breakage of the brushes can be prevented. Moreover pressure of the brushes can be equalized to hold wear of the brushes uniformly.
