In this paper, a mathematical model of the three-phase brushless permanent magnet AC motor drives in abc reference frame is described. A computer simulation of the motor drive is provided which utilized Lab VIEW software. The simulation can be conveniently used to study the dynamic as well as the Steady-state performance of the three-phase permanent magnet AC motor drives; with either trapezoidal or sinusoidal back emfs, under various operating conditions. The simulation results have been given in this paper.
