Abstract：In the radial force wave modulation of motor, harmonic current injection method is an effective method. In this paper, according to Maxwell stress tensor method, firstly, the spatial and temporal distribution model of the radial force wave in the pole slot generated by the electromagnetic action of the surface-mounted three-phase permanent magnet synchronous motor (PMSM) was deduced to determine the harmonic current frequency with compensation effect. Secondly, the single-frequency harmonic current injection compensation model was derived, and the least square method and Newton iteration method were used for parameter identification. Thirdly, the coupled radial force wave model was derived and the least square method was used to identify the parameters. Finally, the compensation model of multifrequency harmonic current injection was deduced. The model is verified by Ansys simulation and prototype experiment.
