More Information
Summary:The invention comprises a motor brush holder assembly including a brush holder member and a brush member which is free for reciprocal longitudinal motion in said brush holder. The assembly includes captured brush spring means for urging longitudinal motion of the brush in one direction. The configuration of the holder is such as to confine the brush spring within the holder. The brush spring confining means may include a planar member between the spring and the brush. The cross section of the interior of the holder may exceed that of the brush; or a portion of either the planar member, or of the brush spring, may project through a slot of the brush holder which does not extend the full length of the holder. By this means there is an assurance that the brush spring cannot project beyond the front of the brush holder and make contact with the commutator.
