A Full-Period Generating Mode for Bearingless Switched Reluctance Generators
A bearingless switched reluctance generator (BSRG) is developed, which is operated in full-period generating mode. In the proposed 12/8 bearingless generator, two sets of windings are embedded in the stator. The coils of excitation winding wound on each stator pole are separately controlled, whereas the coils of generation winding are connected in series for each phase. To begin with, the voltage equations of the generator are built for the dynamic analysis model. Then, the mathematical model of radial force is derived for the control of the unbalanced magnetic force. Furthermore, a control algorithm is introduced to generate the required radial forces and output voltage. Finally, dynamic analysis results are included to verify the proposed analysis.
