M.Sc. Tezi Görüntüleme
Direct current (DC) Motors widely used in industrial applications. Nowadays DC motors are finding many applications in household appliance, hence speed control of DC motors are also many important. Some of its widely familiar application are cassette players, hair dryers, drills and mixers.
The main objective in this master thesis is to study PLL (Phase Locked Loop) usage for control of DC motors speed.
In this thesis, subjects are submitted in the following order; first DC motors are introduced and in the next section working of transistor to be a key and structure of coppers are mentioned. Then work of PLL and components of PLL are expressed one by one. Consequently, the speed control of DC motors is made by designed PLL. Then results and points of view are explained.
