Optimization of Permanent-Magnet Spherical Motor Based on Taguchi Method
IEEE Transactions on Magnetics, 2020 The finite-element model is established to simulate electromagnetic forces of a permanent-magnet (PM) spherical motor using the commercial software from Ansoft. The Taguchi method is used to optimize the magnetic field density in the radial air gap and the maximum torque of the PM spherical motor.
