Abstract
This paper presents a general expression of back-EMF constant of 3-phase permanent magnet brushless DC (BLDC) motor with nonoverlapping stator winding. From the expression, any possible combinations of pole and slot numbers are found and the value of back-EMF constant is compared in the several cases of different pole to slot number ratios and airgap flux density waveforms
