Master thesis contains development of communication between BLDC motor and external system. First part describes development and realization of microcontroller system suitable for use in electric scooters or small electric vehicles. It contains design of circuit and printed circuit board with microprocessor which oversees motor status and peripheral units to protect electrical components and the user operating the vehicle. The second part describes development and realization of the system for use in automatic measurement of different parameters for diverse electric motors, which have different torque characteristic and efficiency. This allows easier testing of the motors and comparison between different versions for more efficient development. In this microcontroller system the data isn't send to a display, but is instead to a computer, where it's saved. How it's saved is controlled by the user who can also choose different measuring procedures. During testing the controller sets the input parameters of the motor until they reach the desired levels and then triggers the signal to save data. This allows simple measurements of motor parameters in different states of operation.
