Practical Dynamic Modeling of Brushless DC Motor Using the Analytical Back EMF Prediction

This paper presented the practical dynamic modeling of BLDC motor. The analytical back EMF prediction is employed for proposed method. The back EMF result is confirmed by the finite element method and the experiment. Also, the proposed method provides more the precise voltage and current waveform in the BLDC motor than the conventional method. The validity of the results is successfully verified by the experiment, along with high-speed DSP, TI TMS320F2812.
