Feasibility study of the choice of electric drives of metal-cutting machine tools.
Abstract
Analyzed the costs of electric machine tools. It is shown that when comparing and selecting options, you can limit the calculation of the cost of the drive only if the performance and load of the machine do not change over time. Expressions for calculating the reduced cost of the drive are given, which simplify the technical task -economic comparison of electric drive options and more fully take into account their influence on the performance of the designed metal-cutting machine.
