Abstract

In this paper, the electromagnetic processes in a coreless synchronous machine with a superconducting excitation winding and a stator winding connected by a zero-flow scheme at a skewed rotor axis are considered. It is shown that, in conditions of “pure” nutation, the zero flow contours do not function, and this machine operates as an ordinary synchronous machine. In this regard, the moment of nutation is formed due to the interaction of the unperturbed stator current with the perturbed excitation field and is, therefore, dependent on the load angle. When the longitudinal (in the sense of Gorev) current of the stator changes sign, the moment of nutation also changes its sign and can become either stabilizing (reduce the angle of nutation) or destabilizing. The destabilizing nature of the moment of nutation can appear at small load angles. The basics of this machine theory are described.

具有自调节磁悬浮转子轴的同步电机的特性

摘要

在本文中，考虑了在具有超导励磁绕组和定子绕组的无铁心同步电机中的电磁过程，该定子绕组通过零流量方案在偏斜的转子轴上连接。结果表明，在“纯”章动条件下，零流量轮廓不起作用，并且该电机作为普通同步电机运行。在这方面，由于未扰动的定子电流与扰动的励磁场之间的相互作用而形成章动力矩，并因此取决于负载角。当定子的纵向电流（在Gorev方向上）改变符号时，章动力矩也改变其符号，并且可能变得稳定（减小章动角度）或不稳定。章动力矩的不稳定特性可能出现在较小的负载角下。
