Abstract
The paper describes an improved two-dimensional (2-D) analytical model for predicting the winding inductances and the armature reaction fiel d of slotless permanent magnet brushless machines. Results from the mo del are compared to those deduced from finite element analyses, existi ng one-dimensional (1-D) and 2-D analytical models and measurements. I t is shown that the radial thickness of the airgap winding can have a significant effect on both the winding inductances and the armature re action field.
