Abstract :
2-D analytical models have been developed and validated for the calculation of the airgap and slot components of the self- and mutual-winding inductances of brushless motors, having either overlapping or nonoverlapping stator windings and surface-mounted permanent magnets. They can account for the effect of curvature and the large effective airgap, the slot openings and aspect ratio, and the disposition of the coils. The models are used to investigate the effect of design parameters on the winding inductances
