Brushless DC (BLDC) motors are becoming increasingly popular in automotive sectors (particularly electric vehicles (EV)), HVAC, white goods and industrial uses due to the elimination of the mechanical commutator used in traditional motors, replacing it with an electronic control device that improves the reliability, adaptability and durability of the unit.
Due to the increase in popularity BLDC motors are becoming more and more common even in the education sector such as using them for smaller quadcopter projects and also conducting laboratory experiments with them as teaching material in universities.
This is also the case at my university, the Budapest University of Technology and Economics where during electronics labors we often came across the working mechanism and control of Brushless DC motors.
Therefore, the goal of my thesis is to create a Printed Circuit Board (PCB) which can be used to drive BLDC machine to be used in the university laboratory by the students who can make various controlling designs for it.
In the course of my thesis I briefly summarize the information about the BLDC motors and then describe the process of designing the circuit in detail, and finally run some tests on it.
