摘要

提出了一种开关磁阻电机的新结构，其中绕组被布置为在电机内提供短磁通路径。这减少了在气隙中建立磁通所需的电流。电动机有奇数个相绕组，其中5个或7个预计是最佳的。一种新型的功率转换器也被开发出来，使这些电机的控制不需要过多的功率开关。采用有限元方法模拟了短磁链的影响。设计并制造了一台七相电机样机。试验结果表明，新设计在性能上有所改善

A new magnetic flux pattern to improve the efficiency of the switched reluctance motor

A novel configuration of the switched reluctance motor is proposed in which the windings are arranged to provide short flux paths within the motor. This decreases the current required to establish the flux in the airgap. The motor has an odd number of phase windings with five or seven predicted to be the optimum. A novel power converter has also been developed which makes the control of these motors possible without excessive numbers of power switches. Finite-element analysis was used to model the effects of the short flux loops. A prototype seven-phase motor was designed and built. Test results are presented which indicate the improvements in performance offered by the new design.<>
