摘要
A two-dimensional analytical method for predicting the axial component of the electromagnetic fields in the airgap/magnet region of a permanent magnet (PM) disc-type machine is presented. The effects of stator slotting upon the electromagnetic fields are being accounted for by the introduction of a 2D relative permeance function. The more refined permeance distribution is derived by calculating the flux waveform directly from conformal transformation. The computed results obtained by 2D analytical method are validated by those obtained from the more accurate, though a lot more complicated, 3D finite element analysis.
