Trojfázové asynchronní elektromotory pracující trvale v protiproudé brzdě

Abstract

This bachelor work focuses on analyzing function of induction machine, function of asynchronous countercurrent brake, the energy balance system for countercurrent brake and is annalyzed torgue characteristic of induction machine. To evaluate the characteristics and properties of induction motor were made no-load measurement , short-circuit measurement and torgue characteristics. The end of bachelor work summarized results of measurements including for example diagnostics of no-load power dissipation and current, of short-circuit power dissipation and current and of measurement of torgue characteristic.
