传统的电励磁双凸极电机(doubly salient electro- magnetic motor，DSEM)通常采用6k/4k极结构(k为正整数)，每个励磁元件匝链3k整数倍相绕组，各相磁路不一致且每相磁链最小值与最大值处的变化率不同，因此磁链、反电势波形的对称性较差。此外，传统 DSEM 通常采用三相三状态的控制方式，对应相绕组在电感最大值处换相时会产生负向转矩，加剧了DSEM的转矩脉动。本文研究一种新型12/10极DSEM，根据相差180°电角度的两相绕组的电磁特性存在互补关系的规律，将六相绕组两两反向串联构造成一种低转矩脉动DSEM。场路联合仿真及实验结果表明：两两反向串联后电机磁链、反电势的对称性得到很大的改善，并且随着转子位置角的变化，相绕组自感基本保持恒定。在此基础之上采用三相六状态控制策略电动运行可以获得与永磁无刷直流电机相似的转矩性能，因此得到了一种低转矩脉动DSEM的优选方案。“,”Traditional doubly salient electro-magnetic motor (DSEM) usually adopts 6k/4k stator/rotor pole combination and each excitation coil corresponds with 3k integral multiple armature coils. This configuration inevitably leads to the asymmetry of the magnetic circuits among phases as well as the different rate of change around the maximum and minimum flux linkages, thus causing the asymmetric contour of the electromotive force waveforms. What’s more, the control strategy of three-phase three-state is usually conducted with traditional DSEM, which generates torque gap at the each commutation time when maximum self-inductance arrives, hence leading to the increment of torque ripple. In this paper, a novel 12/10 DSEM has been presented. Based on the mutual complementarities between the windings whose electrical angle difference is 180°, the scheme of series-opposing connection is adopted to create a new DSEM with minimum torque ripple. The results of simulation and experiments demonstrate that: the symmetrical characteristic of flux linkage and EMF waveforms are significantly improved and the self-inductance maintains almost constant with the change of the rotor position angle. Based on that, the control strategy of three-phase six-state is conducted with a prototype, and the torque performance even comparable to permanent magnet brushless DC motor is obtained, thus providing an optimal scheme for DSEM with minimum torque ripple.
