N2 - An interior permanent-magnet synchronous motor (IPMSM) used for high-performance industrial servo applications is investigated. Compared with surface mounted PMSM, the IPMSM features simple fixing of permanent magnets. However, torque ripple reduction is still an important issue. Three rotor structures are comparatively studied by the finite-element method (FEM) in this paper. The optimizations of rotor eccentricity for models of 48-slot/8-pole, 36-slot/8-pole and 18-slot/8-pole are investigated, respectively. Moreover, the influences of the permanent magnet (PM) width, the PM slot span angle and the width of slot notch on torque ripple are also discussed.
