Impact of Electric Drives in Efficient use of Electric Machines

Abstract

This paper will illustrate the impact of electric drives in the efficiently use of electric machines. The Induction, Permanent magnet synchronous and Synchronous reluctance machines will be considered when making this study. The earlier and modern use of electric machines will be shown for comparison, the development of drives and their impacts on frequent standard revisions and on the drastically use of the new types of machines are shown. The energy control and management through drives control in cranes, elevators and escalators applications will be discussed and finally the conclusion will be made based on the highlighted figures.
