The use of combined windings for contactless measurement of speed in linear asynchronous electric drives.

Abstract

The possibility of contactless measurement of the speed of electric drives with linear asynchronous electric motors using the combined stator winding is shown. A theoretical analysis of the operation of a contactless speed sensor using phase current and voltage unbalance inherent in LAD is given. Experimental data on measuring the speed of a linear electric motor using a combined winding are given. Il 3. Bibliogr .: 4 titles.
