This thesis presents the development of a system for electric testing of brushless direct current motors stators. The system must be capable of performing 4 typical electric tests: high voltage withstand test, measurement of wound resistance, surge test and measurement of GND contact resistance. The entire course of development, from basic design, selection of appropriate components, development of the program and final assembly is presented. Potential electric tests were studied and described. The main safety elements and safety circuit is presented. Key part of the development was to sensible design the software, which was used not only to change test settings and test control, but also for all automatics of the device. Software was divided in two separate parts, main program and control part. For reliable functionality of the system, the robust communication between the program parts had to be implemented. All system components are through the network switch connected to the same local network, enabling seamless communication. Functioning of the instrument and the entire system has been tested with a series of test samples. The final result is working testing device, which is used in smaller production process.
