Characteristic Analysis of Bi-and Uni-polar Drives of Reluctance Motors

摘要

The comparative studies on the torque characteristics of the reluctance motor for bi- and uni-polar sinusoidal drives are given. The 3-phase test motor with 6/8 stator and rotor pole combination is used for the non-linear FEM analysis and experiments. The analysis shows that the different flux paths are produced, depending on bi-and uni-polar current drives, which makes two significant differences in torque-current characteristics.
