Abstract:
An electric power steering system and its brush motor are disclosed. The brush motor includes a stator and a rotor rotatably mounted to the stator. The rotor includes a rotary shaft, a commutator and a rotor core fixed to the rotary shaft, and a rotor winding wound around the rotor core. The commutator includes a plurality of commutator segments. The rotor core includes a plurality of teeth. The rotor winding includes a plurality of winding elements. Adjacent teeth define therebetween wire slots for receiving the winding elements. The winding elements include a plurality of first winding elements and a plurality of second winding elements. The first winding elements are connected in series through the commutator segments. The second winding elements are connected in series through the commutator segments. The first winding elements and the second winding elements are received in different wire slots. Implementation of the present invention can improve the reliability of the product.
