Srovnání vybraných parametrů asynchronního elektromotoru napájeného z měniče frekvence.

Abstract

This diploma thesis is focused on measuring and comparing of the parametres of two transducer inventers Allen Bradley powerfix 40 and Siemens micromaster 440. The theoretical part of this project describes asynchronous drives with the frequency inverter, their historical development, distribution, control methods of asynchronous drives with frequency inventers, parametres of asynchronous engines and frequency inventers and finally features of asynchronous engines powered from frequency inverters. The practical part describes concrete results of measuring of selected parametres and quantities of drives with frequency inverter and subsequent comparison of them.
