Moallem Department of Electrical & Computer Engineering,Isfahan University of Technology Journal Article 2007 01 31 Although there are analytical methods for field calculation in surface-mounted synchronous motors, accurate analytical methods for predicting airgap flux density distribution in Interior-type Permanent-Magnet (IPM)synchronous motors are not available. In this paper, a novel method for analytical prediction of flux distribution, based on Schwarz-Christofell transformation techniques, is proposed to evaluate the airgap flux density distribution in an IPM motor. To validate the accuracy of the new analytical method, the results are compared with transient Finite Element Method (FEM) results. https://scientiairanica.sharif.edu/article_2595_453fadbd8a1a3af50a9df4df899537b5.pdf
