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. Since the unipolar current drive produces shorter flux path and, therefore, higher air gap flux density, higher torque for the given winding current can be expected. Another important point is the effect of magnetic saturation. The examination of the yoke flux with respect to various rotor angles suggests the yoke is apt to be saturated in the bipolar current drive.<br>The experimental verification has been made by using the test motor. From these experiments and analysis, it is concluded that the unipolar sinusoidal current drive is preferred to have a linear relation between torque and current and to avoid the effect of magnetic saturation.
