Permanent magnet synchronous motors are widely used in electric vehicles. The permanent magnet synchronous motor torque ripple suppression is a research hotspot at present. This study adopts the torque ripple equation based on magnetic co‐energy. Two novel minimum current harmonics torque ripple suppression strategies based on the magnetic co‐energy are proposed. Both methods are suitable for whole current map calculation. One is based on dq‐axis model, which makes the dq‐axis current harmonics fluctuate along gradient direction of the torque equation to dq‐axis currents. The other one is based on the newly proposed torque–current coupling model. The minimum current harmonics obtained by the two methods are basically the same. At last, finite element method and test bench experiment are used to verify the two methods. Both of them can effectively suppress torque ripple.

Modelling of the permanent magnet synchronous motor (PMSM) torque ripple and PMSM current harmonics controlling technology are important branches of PMSM research. Based on the existing linear PMSM model derived from magnetic co-energy, this study considers the variation of PMSM parameters (inductance, permanent magnet flux and cogging torque) caused by magnetic saturation. Then, the harmonic coupling models including flux-current coupling model, voltagecurrent coupling model and torque-current coupling model are deduced. In these harmonic coupling models, the PMSM parameters no longer vary with rotor position but only with current amplitude and phase. Based on the torque-current coupling model, a novel method of obtaining the required injecting currents which could suppress torque ripple is proposed. The validity of the harmonic coupling models and the injecting current solution method is verified by finite-element method.
