Laboratorní úloha stejnosměrného servopohonu

Abstract

The theoretical part of this thesis deals with DC motors. It starts by introducing important milestones in history. This is followed by a description of the basic parts of DC motors and their advantages and disadvantages. After that, the division of motors into groups according to the variation of rotational speed and the principle of operation of the DC machine itself are presented. In the practical part, the design of the laboratory apparatus is described as well as the assignment for the sample laboratory problem. Furthermore, the sample measurement and the elaboration of this laboratory problem are also discussed. The elaboration itself contains an overview of the measured values, relations for important variables and their calculation, as well as graphs for comparison of the measured values with the calculated ones. Finally, a list of the measuring instruments used is given.
