| Abstract: | We propose a new method for analysis of the harmonic wave components of magnetic fields in rotating machinery. Using the magnetic permeability obtained by transient analysis of the nonlinear magnetic field, the harmonic wave components of the magnetic field are individually calculated in the spaces of both the rotor and stator subject to the boundary condition that the harmonic wave components obtained by the transient analysis are set on the sliding surface. Mode separation of the magnetic field will contribute to research on reducing harmful harmonic wave components for rotating machinery. © 2010 Wiley Periodicals, Inc.
