The present utility model discloses a DC motor applied in an electric car. By adopting the motor, problems that the prior common motor is high in price, is not good in working stability and is not convenient for controlling and adjusting can be solved. The adopted technology scheme is listed as follows, the DC motor of the electric car comprises a shell body, an end cover, a motor shaft, a rotor, a stator and an electronic commutator, windings and sensors are arranged on the stator, the number of the sensors is corresponding to the phase number of the windings of the stator, the electronic commutator is connected with the windings of the stator and used for supplying power for the windings of the stator, and the sensors are connected with the electronic commutator. The DC motor is characterized in that a plurality of series-connected windings are arranged on the rotor, and the windings are connected with the electronic commutator through a conductive mechanism and a power line which are arranged between the r
