Conductive Device For a Brush Motor

A conductive device for a brush motor comprising:

• an insulation stand having:
• an open end;
• a closed end;
• a supporting rod mounted in the insulation stand near the open end of the insulation stand;
• and
• a power cord mounted in the insulation stand and having an outer end extending out of the closed end of the insulation stand;
• a conductive sheet being curved, mounted in the insulation stand at the open end of the insulation stand around the supporting rod and having:
• a middle mounted in the insulation stand and electrically connected to the power cord;
• and
• two ends extending out of the open end of the insulation stand and facing to each other;
• and
• a conductive wheel being a hollow wheel, rotatably connected to the insulation stand and having:
• an elastic layer mounted around the supporting rod of the insulation stand, extending out of the open end of the insulation stand between the ends of the conductive sheet and having an external surface;
• and
• a conductive layer mounted around the external surface of the elastic layer and contacting the conductive sheet between the ends of the conductive sheet.
