Krasnoshapka N. Starting regimes of asynchronous electric drive with properties of moment source and with the systems of starting currents limitation

Object of research is the starting modes asynchronous electric drive (AED) with the motors of different constructions at the feed of different systems. The purpose of research: improvement of power efficiency of the starting modes AED at forming moment source properties at an short-circuit rotor asynchronous motors (AM). Methods of research: mathematical modeling, methods of analysis of the electro mechanics systems and nonlinear magnetic chains. Theoretical results: the theory of the dynamic modes AED at the use AM with the ferromagnetic screens of elements of short-circuit rotor puttee at different systems of feed and frequency starting at the current-frequency management by a transformer is developed. Practical results: engineering method of computation of ferromagnetic butt end screens and algorithms of current-frequency management in the process of starting is created. A subject and degree of introduction: mathematical models of starting AM were used at serially production AED in SPU ETAL. Efficiency of introduction: improvement of power and dynamic indexis. Sphere of use: designing AED with AM.
