A Novel Estimation Method of Force-Current Factor using Back-EMF of Radial Displacement in Homopolar-Consequent-Pole Bearingless Motor
The force-current factor is a control parameters in bearingless motors. It is defined as the ratio of the magnetic suspension force and suspension current. We have proposed a method to estimate the force-current factor of the radial suspension force from the back-EMF of the suspension winding. In this study, the force-current factor of a prototype machine was estimated experimentally and compared to that calculated using 3D-FEM analysis.
