Description
Summary:This paper presents the implementation and control of a surface permanent magnet synchronous self-bearing motor. The radial force control scheme is based on the motor which have both the motor windings and the suspension windings. Through a conversion process, the actual motor can produce controllable radial force and rotational torque with only a set of concentrated windings in the stator. The experimental results demonstrate that this motor is able to produce the requested radial forces when it is rotating and subjected to a load torque. Preliminary experimental results for self-bearing operations are also presented.
