摘 要：Aiming at working out how to apply the brushless DC motor to the electric car,a control systemwas designed after a series of related researches.With the basic principles and methods of operating the brushless DC motor being studied,the sirmlation model of controlling the brushless DC rrotor was designed by MATLAB software,and the related parameters were analyzed and studied.The results showed that the brushless DC motor had good controllability,which made it suitable for the application to the electric car.
