Abstract

IPMSMs (Interior Permanent Magnet Synchronous Motors) are widely used for many industrial applications. However, IPMSMs cause large noise and vibration due to torque ripple and radial force. In this paper, 6th radial force caused by harmonic current is analyzed and modelling of 6th radial force is constructed based on flux linkage Based on this modelling, 6th radial force is mitigated by injecting harmonic currents. Firstly, we make some assumptions to make 6th radial force modelling. Secondly, 6th radial force modelling is derived. Simulation results and Experimental results verify the validity of 6th radial force model. Finally, 6th radial force control is performed by injecting dq-axis harmonic current.
