Stanoviště elektronicky komutovaného motoru s bezsenzorovým řízením

Abstract

This master's thesis deals with the design, implementation, and practical verification of a laboratory stand featuring an electronically commutated (EC) motor with sensorless control. The introductory theoretical part describes the construction and mathematical model of EC motors. Furthermore, it analyzes rotor position detection methods, emphasizing sensorless control via back electromotive force (BEMF) zero-crossing detection. The practical part encompasses the hardware and mechanical design of the stand, utilizing Maxon components and a DC motor acting as a load. A key focus of the thesis is the commissioning and parameter optimization of the speed feedback control loop within the ESCON Studio software environment. The proper functionality of the stand and the quality of the configured control are verified through a series of oscilloscope measurements. The result is a fully functional and safe laboratory stand, accompanied by a sample laboratory assignment intended for teaching modern electrical drives.
