Bardavil' I. The control electric drive of the turbomechanisms under the scheme of the valve-type engine with excitation by an alternating current.

The dissertation is devoted to questions of perfections of the control electric drive under the scheme of the valve-type engine(VE)for turbomechanisms. The equations of the basic characteristics(mechanical, electromechanical and electromagnetic moment) VE are received on the basis of the asynchronous machine with the phasic rotor with excitation by an alternating current. The influence of frequency of the excitation current and direction of the rotation field on the power of converters in stator and rotor is investigated. In offered system of the electric drive the lowered speeds is reached by the most economic way by change supply rotor voltage and reverse direction of rotation of the excita tion field.
