Abstract

The efficiency requirements for induction motors are currently on the rise. One of the methods for increasing their efficiency is using thinner magnetic circuit sheets. However, this method also affects many other properties. The aim of this bachelor thesis is to verify the effect of magnetic circuit sheet thickness and quality on the overall efficiency and other parameters of the induction motor. Thesis is divided into three main parts. The first part deals with the description of induction motor, losses in the magnetic circuit, material properties of magnetic circuit sheets and general electromagnetic calculation of an induction motor. The second part describes the chosen solution, including a comparison of properties of sheets used for each sample. The main content of this part is the measurement of samples. The results are evaluated in the final part of the thesis.
