Měření oteplení konstručních částí asynchronního motoru při napájení z měniče

Abstract

The main objective of this bachelor thesis is to measure the warming of the asynchronous engine structural part and to produce consistent values from the heating curves. The theoretical part is dedicated to the asynchronous engine itself. In the theoretical part are described basic data about asynchronous machines, types of machines, principle of operation, characteristics, types of load and thermal process. In the practical part, the main objective was the measurement itself on an asynchronous engine that was powered by a frequency converter. Four thermal sensors are located on the engine structures, which measure the values throughout the measurement period which are then stored in the text editor. From the measured values are then produced warming characteristics.
