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.

Analysis of possibilities to improvement induction motors efficiency
Novotný, Jiří ; Hájek, Vítězslav (referee) ; Mach, Martin (advisor)
In the first part of the master’s thesis dealing with the increasing efficiency of induction motors there are briefly presented basic information about induction motors, followed by an overview of the losses of induction motors. The next part deals with the ways to increase efficiency of induction motors without increasing tooling costs. The practical part consists of four measurements of four induction motors, with their various mechanical adjustments to make comparing benefits of these modifications possible. The measured results are compared by a finite element method in Maxwell 2D Design program, in which the same motors are simulated as measured. Theoretical knowledge about the increase of efficiency is practically applied while being implemented in the simulations.
