The thesis addresses the challenges of automating existing industrial processes and presents a solution for a specific application. During the testing phase of an electric motor at Kolektor Mobility d. o. o., an unexpected torque drop was observed, presumably due to the variation in oil viscosity with temperature. This led to enhancing the current system by replacing the manual control with an electronic valve, allowing for more precise system adjustments—a concept well-suited for thesis exploration.
The initial step involved selecting an appropriate valve, and a serial valve from Bosch was chosen. Subsequently, a dedicated testing station was set up to assess the valve’s performance on a single motor. This required the development of a new LabVIEW program to measure oil flow and pressure within the system. Control was initially manual, enabling arbitrary voltage adjustments on the valve. A new loop responsible for valve control was added to integrate this into the pre-existing testing program. Once successful operation was achieved on a single motor, the code was adapted for twelve motors. Further testing was conducted in an environmental chamber to simulate various ambient temperatures.
The final version of the program sufficiently meets the company’s requirements, though ongoing monitoring and minor parameter adjustments during testing are anticipated. Preliminary testing indicates system stability, suggesting long-term operational reliability.
