Abstract
The invention relates to a commutator and an electric brush, in particular to an improved commutator and electric brush of a rotor magnetic pole winding-type motor. On the basis of the previous application, the improved commutator and electric brush are structurally improved for solving the problem that an existing commutator and electric brush can not normally convert a current positive electrode or a current negative electrode for the motor. According to the improved commutator and electric brush of the rotor magnetic pole winding-type motor, normal current commutation can be achieved on the rotor magnetic pole winding-type motor, and therefore the motor can normally run.
