Commutator commutator segments using copper alloy of silver, cadmium, copper and the like, high-strength molded plastic. Brushes in sliding contact with the commutator, the armature current to provide a rotor winding. Brushless DC motor electromagnetic commonly used metal-graphite brushes or electric graphite brush. Rotor core is made using silicon layers, generally 12 slot motor, Embedded 12 groups armature windings connected in series between the winding motor agency, then, respectively, 12 commutator segments connection. Ordinary asynchronous motor stator windings AC power grid, the rotor windings without connecting with other power. So that the motor manufacturers, it has a simple structure, easy to manufacture, use and maintain, reliable operation and low mass, low cost. Induction motors have higher operating efficiency and better operating characteristics, approaching constant speed from no load to full load range, can meet most of the requirements of industrial and agricultural production of mechanical transmission.
