The investigation and development of rational modes of the forge-pressing machines power consumption

The object of investigation: asynchronous electric drive of the forge-pressing machines. The purpose of the work: the development and investigation of the stator voltage regulation system and additional resistance in the rotor circuit of the asynchronous electric motor with phase rotor. Performed have been the theoretical investigations using the methods of the mathematical analysis, numerical integrating of the differential equations systems, the experimental investigations with application of the measuring and electronic instruments. The method of regulation of the stator voltage and additional resistance in the asynchronous motor rotor circurt, the mathematical model of the system: feeding mains-regulator-asynchronous motor have been suggested for the transient processes study. Developed and introduced has been the system of regulation of the power consumption mode of the asynchronous motor with phase rotor, the algorithm of the semiconductor regulator key control has been offered. The simistor regulator of the electric consumption mode for the asynchronous motor has been introduced in the crankshaft press. The efficiency of introduction: the annual electric energy economy of 10287 kW/h which is 9% of the annual electric power consumption of the press prior to introductionAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
