Revolution counter of high-speed motors
Biječek, Vilém ; Tomíček, Pavel (referee) ; Skácel, Josef (advisor)
This bachelor thesis deals with two issues. Several methods have been explored to measure rotational speed. Primarily the speed of the high-speed shafts. Based on this, it was found that the most suitable method for this experiment is the optical method. The second focus of this work was design and development of the device. A large part is devoted to the selection and application of components, and simulations of circuit connections, which have been successfully tested and implemented. The output is an accurately measured value shown on the display. It also included the design of printed circuit boards, one for analogue information processing and the other for placing the microcontroller with the display.
