Electromagnetic moment of a jet motor with a unipolar excitation of the windings, taking into account the saturation of the magnetic circuit.

Abstract

A method is proposed for approximating the magnetization curve of a RD magnetic circuit with magnetically insulated phases and unipolar excitation of windings, based on which expressions of instantaneous and average values of electromagnetic moment are obtained, taking into account steel saturation, which make it possible to create a more accurate mathematical model of WFD or BD based on RD. The calculated curves of the static synchronized moment of the model of the WFD model are shown, and their comparison with the experimental curves is given. Il 3. Bibliogr .: 3 titles.
