TECHNICAL AND ECONOMIC ASSESSMENT OF GEARLESS ELECTRIC DRIVES WITH LINEAR INDUCTION MOTORS
Description
In the article we consider questions of use of gearless electric drives with the linear asynchronous engines. Constructions of engines, their features and the principle of action in the electric drives of difficult oscillating motion executed on system the frequency converter – the asynchronous engine, deprived of shortcomings inherent in geared electric drives are described. Recommendations for a choice of an optimal variant of the drive of a working organ of the technological machine which is carried out on the basis of determination of value of the gained technical and economic effect are made. Methods of technical and economic project evaluation are offered: a method of a maximum of economic effect and a method of a minimum of the given expenses, their assessment is given. On the example of the grain-cleaning machine Petkus K531A and the roller-deck machine SGR-400 determination of technical and economic effect is made and an economic assessment of upgrade is given. The conclusion is drawn on validity of use of gearless electric drives from linear asynchronous engines in a technology equipment of agrarian and industrial complex due to lowering of energy capacity of technological processes because of an exception of gears and transformers of a type of movement; in some cases increase in an output of the final product due to increase in efficiency of technological process is watched; implementation of difficult oscillating motion allows to look at execution of a row of technological operations with development of new technological machines in a new way
