Abstract
A promising way to optimize the technical and economic characteristics of an ac electric drive is to have it designed based on an executive synchronous motor with an increased number of stator winding phases. However, due to the specific nature of the m-phase (m > 3) synchronous motor determined by the energy transfer by a whole spectrum of spatial field harmonics, electromechanical systems should be developed that take this feature into account. A method to study the adjustment characteristics of an m-phase synchronous motor is used, which is based on spectral vectors of electromagnetic parameters reduced to spatial field harmonics. A multichannel concept of realization of an m-phase synchronous electric drive is proposed, which enables targeted formation of the electromagnetic state of a synchronous motor through all its energy channels as a control object. Various ways of its implementation are considered. The advantages of the multiphase synchronous motor can be realized based on of the forced mutual orientation of the flux linkage vectors and the stator current for higher spatial harmonics, which provides the generation of additional constant components of the electromagnetic torque. This design of electric drives is advisable, in particular, for mobile installations with low-voltage (standalone) power sources.
摘要 优化交流电驱动技术和经济特性的一个可行方法是，在定子绕组相数增加的执行同步电机的基础上进行设计。然而，由于 m 相（m > 3）同步电机的特殊性质是由整个空间场谐波频谱的能量传递决定的，因此应开发考虑到这一特点的机电系统。研究 m 相同步电机调节特性的方法是基于简化为空间场谐波的电磁参数频谱矢量。提出了实现 m 相同步电力驱动的多通道概念，该概念可通过同步电机的所有能量通道作为控制目标，有针对性地形成同步电机的电磁状态。文中考虑了各种实现方式。多相同步电机的优势可以通过强制磁通联轴器矢量和定子电流的相互定向来实现，以获得更高的空间谐波，从而产生额外的电磁转矩恒定分量。这种电力驱动设计尤其适用于使用低压（独立）电源的移动设备。
