Remote control of low voltage motor circuit - breaker

The master´s thesis describes the design of the remote control, which is used as accessories for motor circuit-breaker. The work is based on the concept of control realized in the bachelor´s thesis. Master’s thesis contains a literature review of management method stepper motors with integrated circuits. standards relating to the control and switching low voltage devices were rehearsed. It was compiled schema of an entire unit after designing optimal control section of a stepper motor with integrated circuits, which consists of four parts (power supply, power section for driving an coils of stepper motor, control section and section for driving external devices). Design and realization of PCB are based on compiled schema, PCB was mounted with components and final PCB was recovered. The last part of thesis is about verification a functionality with using measurement of a prototype parameters
