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 modelling is constructed based on flux linkage and 6th radial force is controlled on the ground of this modelling. Firstly, we make some assumptions to lead 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.
