Abstract
Permanent Magnet Assisted Five-Phase Synchronous Machine is analytically modeled in the rotating (dq1dq3) reference frames. The cross saturation and space harmonics are captured in the magnetic flux maps obtained from static 2D finite element (FE) analysis. In this paper, a method to incorporate the skewing effect in the flux map distribution for the first and third harmonic is presented. The original flux for one motor segment is used to calculate fluxes of the first and third planes in the consecutive skewing segments. Respective rotator operators allow to sum the contribution from axial slice and shift the resulting map to the desired zero reference position. Eventually, a dynamic model is established on the new corrected flux maps. FE and experimental validations have been performed to confirm the authenticity of the proposed technique.
