Abstract

FIELD: field excitation systems of vopolo-synchronous machines. The purpose of the invention is to simplify the design and reduce the consumption of active materials. The machine contains a main three-phase core winding with the number of pole pairs p, an additional three-phase winding connected in a star with the number of pole pairs Zp and with additional outputs between the coil groups of one of the phases. Controlled keys and two bridge controlled rectifiers are connected to the field winding of the machine. The phases of the additional core winding are connected to the input of one of the rectifiers, and additional leads to the input of the other. The number of coil groups in each phase of the additional winding is a multiple of three, and the phase with additional leads is connected to the zero point of this winding via a controllable key. The use of an additional winding, selectively releasing the energy of the primary and third harmonics of the field, reduces the consumption of material on the winding, both due to the shortening of the step and due to the decrease in the number of turns caused by the reduction of the winding power, and the number of pole pairs is also reduced. 2 Il.

 the idle speed of the synchronous electrically driven machine and the speed decreasing from the set. In the low current load-narrow modes, the excitation current is minimal, n to excite sufficient energy with the axis of the harmonic field, it is selected to the atushek groups of only one phase of an additional core winding “When the load is added simultaneously with a decrease in the flux of the main harmonic, the third harmonic flux increases the field, which is sufficiently sufficient for preloading at low current loads even at low current loads; tim in accordance with a control characteristic. Extraction of the third-harmonic harmonic field energy in the additional winding is carried out;
