Abstract

The permanent magnet rotor structures had a marked influence on the torque, efficiency, and
power density of permanent magnet synchronous motor (PMSM). This paper presents the design and
comparison of five different rotor topologies of PMSM. The rotor topologies including surface magnet,
decentered magnet, broad-loaf magnet, buried (spoke) magnet, and interior permanent magnet. The optimal
design was established using the Taguchi method and finite element analysis (FEA). The purpose of the
study was to create a design solution for PMSM rotor with high output power, torque, and efficiency for
high-speed spindle applications. The performance characteristics which including magnetic thickness and
mass, magnetic flux density, cogging torque, torque and efficiency were compared and analyzed through a
two-dimensional (2D) transient FEA, and the feasibility of the rotor designs is validated. The results show
that the decentered permanent magnet motor generates the highest magnetic flux density, thus yielding the
highest output power, torque, and efficiency.
