Abstract
Synchronous reluctance motors with multiple-segment rotor structures are considered. The presence of stator slots is taken into account with respect to torque ripple. An analytical model is presented, based on magnetic interaction between d and q axes, due to stator toothing. The effect of skewing is also considered. Its partial effect on torque ripple reduction due to the rotor anisotropy is shown. A closed expression for the torque is obtained, giving the torque ripple as a function of design parameters. Experimental verification of the proposed model is given based on measurements on prototype motors.Keywords
