Abstract

An analytical method used to predict the magnetic field in an interior permanent magnet (IPM) motor, is developed and validated in this paper. By using space harmonic analysis and conformal transformation (or conformal mapping (CM)) techniques, the air-gap magnetic field distribution, with considering of stator slots effect and rotor saliency effect, is precisely calculated. The accuracy of this analytical method is confirmed by the 2-dimensional finite element analysis (FEA). The analytical method can produces results much faster than FEA alone
