Abstract: This study derives a high performance flux barrier for an interior
permanent magnet (IPM) motor using binary-based topology optimization (TO). TO
has a higher degree of optimization than size or shape optimization. An IPM
motor has many design parameters including the current phase angle, core shape
of rotor and stator, and magnet position and shape. The flux barrier in an IPM
motor plays a particularly important role, influencing several characteristics.
We apply TO, using a multistep genetic algorithm, to the rotor core in order to
determine a flux barrier with the highest torque performance.
