DC Motors Analysis and Innovation
Šimko, František ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
The thesis aims to explain the design a prototype of an innovated small engine. It is divided into three main parts. The first part is focused on the analysis of low power DC small engines available on the market. The second part consists of measuring, construction and loss analysis of a DC small engine with permanent magnets. The last part deals with the possible innovations of a small engine with permanent magnets and subsequent implementation of some of them. The innovations are supported by calculations and simulations.
Program for calculation of BLDC motor
Chloupek, Karel ; Janda, Marcel (referee) ; Vítek, Ondřej (advisor)
This thesis focuses on problematics of BLDC motors. Thesis consist of theoretical and practical part. In introduction is the reader acquaint with problematics, principals of development, advantages and disadvantades of BLDC motors. Then folows a description of different types, their realization and construction. Main part of this thesis deals with segment stator. For this type of magnetic circuit was developed computing software. This software will design and provide calculation of motor due to given parameters. In second step, the program generates source code for FEMM software, which provides a simulation. This is the most effective way, how can designer simply verify his calculations
