Abstract

Parameters identification of power electrical equipment for technological objects with complex and non-standard kinematics of working bodies is considered. Operation features analysis for a cold-rolling pipe mill is carried out and the relevance of the design problem of electric drive system is substantiated. The advantages of a field regulated reluctance machine are substantiated considering the peculiarities of the technological operations and equipment. Motor electromagnetic torque parameter is used as criteria for geometry optimization problem. The mechanical stresses calculation of the rotor proposed design for given speeds and loads is performed. The influence of a "jumper" in the radial direction on the strength of the machine rotating parts is shown. The multi criteria optimization task for the configuration of power circuits is carried out according to capital costs and reliability. The effectiveness of a six-phase three-level electrical converter is substantiated. The operation speed of the electric drive of the auxiliary mechanism is increased by almost three times, and the performance of cold-rolling pipe mill is improved by 10-15%. Power circuits configuration for multilevel electric converter ensures a reduction of losses by 1%.
