Improvement Power Parameter of Small Induction Motors
Halfar, Tomáš ; Ondrůšek, Čestmír (referee) ; Hájek, Vítězslav (advisor)
The master’s thesis Improvement power parameter of small induction motors deals with issues of lowering the losses of small induction motors. The first part introduces with design and principles of operation of induction motors. Also introduces to theoretical problematic of losses, their lowering and measuring. In the practical part there are results of the measuring the losses in the induction motor ATAS Elektromotory Náchod a.s. T22VT512 (71-0512). There are proposed methods of increasing the efficiency of induction motor due to measuring and their verification in the Maxwell software. The last part is dedicated to measuring the losses of prototype motor from ATAS and comparison of results with previous motor.

Analysis of steel grade influence on small induction machine efficiency
Plíšek, Oldřich ; Klíma, Jiří (referee) ; Mach, Martin (advisor)
The theoretical part of the bechelors thesis examining the impact of the material of the magnetic circuit on the efficiency of induction motors is devoted to analysis of the induction motor and its losses. It also describes the measuring, including calculations of individual losses. Another theoretical part examines the impact of specific losses on the magnetization characteristics of assessed laminations. The practical part includes laboratory measurements of single phase and three phase motors ATAS Electromotory Náchod brand with multiple types of laminations. Measured values are used to calculate individual losses, which are later mutually compared. Models of measured motors with multiple types of laminations are simulated with the aid of ANSYS Maxwell RMxprt program. Analysis of engines with specific types of laminations are performed with the aid of analytical calculations. Results of calculations are compared with simulated and measured values.
