Abstract
An improved structure for coupling field windings to motor brushes, including a nonconductive brush housing, a conductive brush holder located in the brush housing, a wire guide for guiding the field winding to the tab, the brush holder including a conductive tab extending outside the brush housing and means for electrically coupling the field winding to the tab. The brush holder holds the brush for movement along a predetermined axis. The wire guide guides the field winding to the tab along a predetermined axis which includes a portion extending generally parallel to the predetermined axis.
