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.

Losses reduction of single-phase induction motor
Vaško, Dávid ; Mach, Martin (referee) ; Vítek, Ondřej (advisor)
Bachelor thesis Losses reduction of single-phase induction motor deals with issues of increasing the efficiency of single-phase induction motor JMO90-4S-90 from EMP s.r.o. Slavkov near Brno. The first part deals with the theory of induction motors, especially single-phase motors and analysis of losses in induction machines. The second part deals with the introduction of motor solutions and methods used for loss reduction. In the third part, the thesis deals with the calculating selected parameters, the design of motors in RMxprt, and their modification for improving efficiency. The fourth part deals briefly with the design of motors in Ansys Maxwell, comparison of results obtained from Maxwell and RMxprt with the results from measurement for motor JMO90-4S-90 and comparison of results from Maxwell and RMxprt for other motor solutions.

Improving energy parameters of single-phase induction motors
Dospěl, Leoš ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
Bachelor thesis Improving energy parameters of single-phase induction motors deals with issues of lowering the losses of a small single-phase induction motor J22VV506 from ATAS Elektromotory Náchod a.s.. The first part deals with the theory of asynchronous motors and the issue of losses and their reduction is described in this part as well. In the second part engine parameters are measured and calculated efficiency of the machine and suggested ways to reduce losses. In the last part is measuring motor with the proposed regulation.
