Abstract

The topology optimization by distributing the magnetic material in the design domain, which is called as the ON/OFF method, is attractive for designers of magnetic devices, because an initial conceptual design, that we could not imagined beforehand, may be obtained. We examined how to apply the ON/OFF sensitivity method to the IPM (Interior Permanent Magnet) motor in order to determine the optimal topology of the rotor. A technique to apply the ON/OFF method to the design of motor considering the nonlinearity of B-H curve and rotation of rotor is shown. The effects of the choice of the design region and the phase angle of stator current on the obtained topology of motor core are discussed.
