Efekt posuvu kartáčů na výkon stejnosměrného motoru

Abstract

This thesis focuses on the effects of brush shifting on the performance of brushed DC motors. It begins by explaining the basic operating principles of electric machines and compares them to one another. The thesis then shows the implementation of a simulation model on Ansys Maxwell in order to validate the theory presented regarding armature reaction and demonstrates the possibilities of predicting motor characteristics via simulation. Finally the thesis presents measurements and results performed on an experimental setup to prove and validate the claim of improving motor performance using brush shifting.
