In this paper, first of all the motor performance created by permanent magnetic in a slot
less air-gap of a surface mounted permanent-magnet synchronous motor with non
magnetic rotor and either sinusoidal or mixed (quasi-Halbatch) magnetization using polar
coordinates is presented. After that the analysis works for both internal and external rotor
motor topologies, the effect of stator slots is introduced by modulating the magnetic field
distribution in the less slot stator by the complex relative air-gap permeances and the
conformal transformation of the slot geometry. Finally, the predicted results of flux
density distribution and cogging torque with those obtained by finite-element are
analyzed.
