ABSTRACT:
A commutator brush holder mounts a pair of tension band springs in quadrature relation. Both springs contact the brush end remote from the commutator and urge the brush into contact with the commutator, with constant force. The quadrature springs promote full and intimate contact between the brush and commutator, thereby minimizing brush bounce and tilt and resultant transient signal generation.
