Metody regulace otáček asynchronních motorů

Abstract

The principal thesis deals with main principals of function with induction motors. It describes speed control of induction motors and the individual ways of them. The main point of the theoretical part is the analysis of speef control by changing slip,changing of frekvencion and changing of the number of poles. The most attention is paid for proccesing of practical messerument of each ways of regulation of speeds of control of induction motor,comparison of the practical results with theory and the summary of benefits and of handicaps in using in practice.
