Aerospace Instrument-Making Annotation << Back Automation of obtaining of mathematical models of electric motors with arbitrary composition electromagnetic state variables Bronov S.A. Avlasko P.V. Povalyaev V.A. Ermakov R.A. Chereshkevich S.V. Nikulin N.A. Marareskul A.V. Lipunova S.Yu. Usov V.P. This paper describes a technique to obtain mathematical models of electric motors with an arbitrary choice of the electromagnetic state variables. The technique was tested on the well-known models of inductor motors of double-way feed with obtaining the expres-sions that contain only currents, only flux linkage, as well as flux linkage of all windings of a stator and currents of all windings of a rotor, flux linkage of all windings of a rotor and currents of all windings of a stator for three phases. For three-phase electric motors such models are given in the literature, and a comparison with them confirmed the correctness of the obtained expressions. This allows you to confidently use them for all the other models and options electromagnetic state variables. The obtained expressions are used in the development of a mathematical model of inductor motor of double-way feed in the design of one of the variants of the experimental electric drive for spacecrafts. Key words: mathematical model, AC motor, inductor motor, system of the automated design, spacecraft. Contacts: E-mail: avlasko@gmail.com Pp. 03-08.
