Abstract—In this paper, multi-layer interior permanent
magnet design is proposed for the torque ripple reduction design
in an conventional single layer interior permanent magnet
synchronous motor(IPMSM). With the help of optimization
analysis in response surface methodology(RSM), the reduction of
the torque ripple in the IPMSM multi-layer design is achieved by
improving the characteristics of the Total harmonic
distortion(THD)of the back e.m.f and the cogging torque. The
validity of multi-layer IPM design for reducing the torque ripple
of the IPMSM is well proved by finite element analysis results
comparison between the prototype single layer IPMSM and the
multi-layer designed IPMSM model.
