In this paper, the effect of armature reaction on asymmetric distributions of permanent magnet (PM) eddy current loss and temperature in a double-layer V-shape interior permanent magnet synchronous machine (IPMSM) for electric vehicles is investigated. Lumped parameter thermal network model and analytical method are established to predict the average temperature distribution and identify the hotspot in the winding. 2D finite element analysis (FEA) is used to calculate PM eddy current loss distributions and other loss density distributions, which are coupled into the 3D thermal FEA model to investigate the PM temperature distribution. It reveals that the phase currents with different advancing angles lead to asymmetric eddy current loss and thermal distributions among PMs of the same pole.
