Měření oteplení konstručních částí asynchronního motoru při napájení ze sítě

Abstract

This bachelor work deals with an asynchronous machine, more precisely its warming characteristic. In a theoretical part there is described especially a construction of an asynchronous machine, its problems of starting-up and possibilities of a regulation. Then it is described a warming characteristic and a graphic construction of a steady-state warming. The main topic of a practical part is measuring of warming characteristics of the asynchronous engine during a power supply. It is maintained by the help of four temperature-sensitive elements which are placed on a construction part of the asynchronous machine and they record all time when the engine is loaded by nominal figures. These figures are then recorded graphically and also by the help of saving of measured data into a text editor.
