Kachura A. Induction rheostats with improved mass and dimensions parameters for induction motors with wound rotor

The dissertation is devoted to development of a technique for research design and elec-tromagnetic parameters of induction rheostats for diminution their mass dimensions parame-ters and increase of adaptability of manufacturing. In work expedience of application of induction rheostats is grounded in the circle of phase rotor of asynchronous engines with the purpose of increase of efficiency and reliability of a lifting-transport equipment. The analysis of the most widespread constructions of IR is executed on his basis classification of IR is created after the degree of change of electromag-netic parameters. Possibility of correct description of AD is well-proven jointly from IR by combining of equalizations, based on the chain models of AD with the field equalizations which describe IR. The method of calculation of thermal processes is developed in IR, that is based on the method of eventual elements taking into account electromagnetic processes in the rotor circle of AD. The structure of experimentalcomplex which will realize the qua-sistatic and dynamic modes of research of AD from IR is grounded and developed. Created computer-assisted complex which provides the analysis of thermal processes in IR.
