Experimental Investigations on a Heteropolar Electrodynamic Bearing-self-bearing Motor

This article describes how multifunction windings can passively generate electrodynamic centering forces and when fed by a power supply, a driving torque. It shows the experimental EMF measures, both for the electrodynamic centering and for the motor functions, obtained on a prototype, operating in quasi-static conditions. It also shows the measured radial forces and the measured torque in these conditions.
