| Abstract [eng] |
The master thesis presents research of the operation characteristics of brushless drive ventilation system. In literature analysis of brushless DC motors are identified advantages against conventional DC and AC motors. Also it is reviewed electronically commutated motor structure, types of construction and recent studies of these motors. In theoretical part are described EC motor operation and control methods. A mathematical model of motor with fan load was designed. It is overviewed simulations models of EC motors. In research part are investigated brushless drive simulation models using „Matlab Simulink“ software. It was designed and manufactured experimental stand for EC fan operation researches. For this purpose researches methodology is presented. Structure: introduction, analysis and overview of brushless drives, aims and objectives of research, theoretical part, research conclusions and suggestions, references. Thesis consist of: 86 p. text without appendixes, 66 pictures, 8 tables, 45 bibliographical entries. Appendixes included. |
