Modeling and Simulation of Brushless DC Motor with Nonideal Back EMF

, 2011
The back electromotive force (EMF) waveform of brushless dc motor (BLDCM) is trapezoid. But it is not absolutely trapezoid because of motor manufacturing. In this paper, a method of modeling for BLDCM with nonideal back EMF is presented.
