Abstract :
A 2D analytical model is developed for calculating the self- and mutual-winding inductances of brushless DC machines having surface-mounted permanent magnets and non-overlapping stator windings. The model is validated against both finite element analyses and measurements, and used to predict the influence of machine design parameters
