Abstract
Energy Saving is just one of many reasons for using Electric Variable Speed Drives (EVSD’s), but the main topic of this Paper. We describe the presently dominating technology, which are called the classic EVSD topology. The typical Energy Saving potential and some typical Converter and Motor efficiencies are given and discussed. The Market situation for EVSD’s is commented. Some new EVSD development Trends, such as Motors with integrated Converter, Motors designed for Converter operation and High Efficiency Motors, that are relevant to the Energy Saving perspective, are discussed. Online Energy Optimisers are described and some practical results presented. The possibilities for optimised operation with Process Machinery designed for EVSD’s are pointed out. The new EMC-directive (Draft), setting up some demands to the Converter, which will affect both the Cost and the Efficiency, is briefly commented.
