Optimum Design of Interior Permanent Magnet Motor for Automotive Cooling Device

Abstract:

In this paper, we developed stator and rotor shapes of interior permanent magnet type brushless motor for automotive cooling device in order to obtain better performance than the prototype. Response surface methodology (RSM) is employed in this paper as an optimization method. Finite element computations have been used for numerical experiments on geometrical design variables in order to determine the coefficients of a second order model for the RSM. The optimum design results confirm that desirable improvements in cogging torque, back-EMF and THD are achieved.
