Abstract :
This study describes the influence of the mutual inductance between the adjacent phase windings of variable reluctance motor (VRM) and presents a new type of inverter for the reduction of such influence. In this inverter topology, though an additional power switch is used as compared with the conventional C-dump inverter circuit, unwanted negative torque produced by the mutual inductance in the winding next to the energizing phase is remarkably reduced. Hence the circuit results in an increase of the average torque and contributes to the improvement of overall drive efficiency. Theoretical prediction is verified by experimental results obtained with the integration of the presented inverter and a prototype 6/4 VRM.<>
