Abstract: In order to enhance the performance of motor, the new DC motor  was presented. Then the winding structure of the new DC motor was introduced and its working principle was analyzed ,  the motor’s mathematics model was established and  simulation model based on Simulink was analyzed. By comparing the winding current waveforms and the total current waveforms under different load conditions which were derived from the simulation model with the actual experiment results, the models were proved to be right and exact. The torquespeed curves were further studied by using the simulation models, the differences and their causes with the simulation results and experimental results were illustrated.The simulation results show that the  torquespeed curves of the new DC motor  is hard and the torque ripple is small.
Key words:new DC motor；torquespeed curves；simulation/Simulink
