摘要：
This paper deals with torque harmonic characteristics of interior permanent magnet synchronous motor (IPMSM) with concentrated winding. In particular, torque ripples including EMF harmonics and cogging torque are numerically investigated with the nonlinear finite element method (FEM), and torque harmonic components are identified with Fourier fast transform (FFT). In particular, the novel design methods to compensate the specified torque harmonics are proposed, and its effectiveness are clarified according to the representative control strategies for IPMSM, maximum torque per ampere (MTPA) and flux-weakening control.
