Abstract :
The mathematical model of brushless dc motor system (BLDCMS) is proposed. First, the BLDCMS is researched including the motor, inverter and controller. The key mathematical model of inverter drive circuit is established by introducing an impulse function and Fourier transform. This mathematical model converted current loop output voltage into actual PWM voltage that representative the inverter switching on or off. Therefore the BLDCMS model could be established easily according to the inverter model. Next, the simulation results and experiment results are presented respectively, confirming the validity of the proposed mathematical model. The simulation results show that this BLDCMS model is correct and meet the requirements.
