In thesis we explain the basic theory of asynchronous motors, we explain the structure of frequency inverters, principles of working and impact on working environment as electrical device. We get to learn the behavior and what to be consider when controlling variable torque loads with frequency inverter. And at the end we tried to summarize and used the knowledge we gain through the thesis on practical case.
The objective of the thesis is to identify and shown possible energy savings at loads like fans and pumps controlled by frequency inverter. On practical case we explain and shown achieved energy savings results.
