All Electrical Panel & Electric Motor Winding

Modern low-cost universal motor, from a vacuum cleaner. Field windings are of copper wire, toward the back on both sides. The rotor's laminated metallic core is gray, with darker slots for winding the coils having high efficiency. The similarly shaped metallic commutator (partly hidden toward the front) has become dark from use. The large brown molded-plastic piece in the foreground supports the brush guides and brushes (both sides), as well as the front motor bearing.
