| Abstract: | Brushless DC motor has been widely applied to the various industries due to its merits of simple structure and flexible speed control, especially in the field of automotive electronics. In this paper, the working principle and mathematical models of the brushless motor are analyzed and researched with the emphasis on the discussions of the motor＇s control strategies while it is in starting and sudden load change. The models are verified and analyzed by means of Matlab/Simulink, the simulation results indicate that the established models are of well availability and stability. |
