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.
