СOMPARISON OF THE ECONOMIC EFFICIENCY OF ALTERNATIVE ELECTRIC DRIVES IN UNSTEADY MODES

Abstract

A comparison of electricity consumption by two types of electric drives for crane rotation mechanisms: rheostat control and electric drive frequency inverter-induction motor. The calculation for a concrete mechanism with given determined operation mode was made. Research has proved that for a given operation mode of payback inverter is 3,5-5,5  years.
