The goal of the thesis was to design and develop a motherboard for a test device that will accelerate and facilitate the testing of a motor controller. The purpose of the motherboard is to integrate all measuring instruments, power supplies and signals from the motor controller. Single-board computer RPI is then used to capture all the measurements and to generate a report, which will ease up further development of the motor controller. The main task of the motherboard is to automatically switch phase signals between different motors supported by the motor controller. Prior to the development of this motherboard, all measurements were performed manually. This was very time-consuming, as all the measuring instruments and power supplies had to be individually set up and manual switching between different motors and signals connected to the motor controller was required. All these settings and switches will be now performed by the RPI through the motherboard. It will only require a written test sequence to execute the test completely automatically. This will save a significant amount of time that can be redirected to further development of a motor controller. The motherboard consists of relays, a 5V power supply, an RPI, an STM23 microcontroller, communication drivers and several integrated circuits for signal processing.
