Dynamometr pro malé výkony

Abstract

The content of this thesis is a brief theoretical analysis, design and practical realization of the low power dynamometer, which is designed for use in teaching vocational subjects taught, Department of Electronics VSB - TU Ostrava. Theoretical analysis of possible solutions of power converters is done at the beginning of this thesis, used motor and its management taking into account. Followed by design and practical implementation of mechanical and electronic components of power dynamometer utilizing DC motor with permanent magnets, using a microcomputer control system with digital signal microcontroller MC56F8023. Its software provides speed control loop with a subordinate power look for the engine of dynamometer, software also provils the control and user communication with the operator via a terminal program running on a PC through an external D / A converter providing power waveforms and the speed of the dynamometer engine. The last part of the thesis contains the measured results with the evaluation of possible use.
