Abstract [en]

The brushless DC (BLDC) motor is a crucial component of our modern

society and exists in a number of everyday items. It is an evolution

of the conventional brushed DC motor. It has several advantages

compared to the brushed DC motor including less maintenance and

better control and precision of the rotary displacement. The goal of

this project is to construct a BLDC motor made by 3D printed plastic

parts and a control system using Arduinos. The purpose of the motor

is that it will be used to demonstrate its functions and to educate

engineering students at Uppsala University in electrical propulsion

systems. Therefore the motor is designed with educative purposes and

it is supposed to be easily controlled by an operator with clear

indications of the internal workings. The finished motor consists of

a stator which holds six electromagnets placed equally distanced from

each other that makes up the tree different phases. In the middle of

the stator a rotor is placed which holds four poles of permanent

magnets with different polarity. The position of the rotor is

determined and controlled by placing three equally distanced hall

sensors in the stator. The signals from the hall sensors is sent to

the Arduinos which in turn control the polarity of the electromagnets

and make the motor rotate. The control system is contained in a

plastic box with controls for different modes available for the

operator and also indications of the position of the rotor and

polarity of the electromagnets.
