Abstract

This paper presents a first topological optimization approach for a sinusoidal interior permanent magnet synchronous machine. A coupled nonlinear 2D FE-GA technique was used. The goal of the optimal design was the synthesis of a maximal sinusoidal back-EMF and simultaneously the minimization of the cogging torque. Two novel rotor topologies for minimal cogging torque and maximal, sinusoidal pole flux were already implemented in series production
