ing winding. It is a symmetrical three-phase winding, the symmetrical three-phase windings connected to the star-shaped, and connected to the shaft on the three collector ring, and then through the brush to the rotor winding connected with the external circuit. V. ConclusionР The use of motors in the country more and more, but the efficiency is not high. In the understanding of the basic principles of the motor, with the deepening of the understanding of the motor, the future will have more efficient motor production. This article simply provides the basic knowledge of the motor is to facilitate the reader a better understanding of the motor.Р referencesР [1] Sun Jianzhong, Liu Fengchun. Motor and drag [M].
