Abstract :
In this paper, the new vector control scheme of BLDCM producing loss-minimized ripple-free torque based on the d-q-0 reference frame is presented including 3 phase unbalanced condition. The optimized phase current waveforms that are obtained by the proposed method can be reference values that the motor winding currents are forced to track by a delta modulation technique. As a result, it can be shown that the proposed work provides a simple and clear way to obtain an optimal motor excitation current
