Abstract :
Based on the mathematical model of brushless direct current (DC) motor, this paper uses the Simulink to model and emulate the brushless DC motor control system. The models of back EMF and current control module are obtained by using the look-up table. Thus, the system is more intuitive, more streamlined and easier to change models. The current and the torque waveforms got from the simulation are basically the same as the waveforms got by the time stepper finite element method. It shows that mathematical model and the simulation method are correct.
