Abstract: This master’s thesis is dedicated to researching the universal system (controller) for controlling three-phase BLDC motors and proving the feasibility of its repair and restoration. The work describes the construction of BLDC motors, block diagram, and schematic electrical principle, as well as common faults of the controller board and their elimination. The next stage involves analyzing existing methods of controlling BLDC motors. In the practical part of this work, the BLDC motor control board was restored and configured using the ST-Link V2 programmer, which was used to load a new firmware onto the STM32/GD32 microcontroller. Also, a working model of a children’s electric tricycle was created, the electric system of which is based on a BLDC motor, which operates on the basis of our restored and configured controller board. The results of the work allow us to conclude that the repair and adjustment of the universal system (controller) for controlling BLDC motors are entirely justified. Therefore, popularizing and increasing the accessibility of the service for repairing and tuning the BLDC motor control board becomes not only an economically viable solution but also a key step in promoting sustainable development and resource conservation on our planet. The purpose and main task of this work were to prove the feasibility of repairing the BLDC motor controller. The object of the study is three-phase BLDC (brushless DC) motors. The subject of the study is a universal control system (controller) for three- phase BLDC motors, including methods and control algorithms. List of used sources: 1.
