how to make a brushless motor at home

Let’s make an electric motor that rotates using neodymium magnets and wires.It shows how an electric current turns into motion. We are building an initial brushless DC motor. It’s not a performance or design award winner, but we like to think that a simple example makes it easy to see what’s going on.
The rotating part of an electric motor is called a rotor. Permanent on the rotor of most brushless motors There are magnets. Our magnets rotates with a dc motor rotor. This effect is commonly. We stuck two neodymium magnets on the outer edge of the rotor, 180 degrees apart. Both are oriented towards their North Poles.
This is different from BLDC motors which have rotating magnets. This simplicity made our electronic circuitry a little easier. How do we turn this thing around. We can only shake it with speed controler but we are looking for a magnetic push. Bring another magnet closer to the rotor coils electric magnets This will cause the magnets to retreat, or push, causing the magnets to rotate. If we push the magnet so hard that it can rotate the magnets halfway, we can turn it towards the next magnet. If we were fast enough, we would keep the magnet close and take it away and keep rotating the magnets. This is where electronics come in. We need to make an electromagnet that will turn the rotor magnet on and off. A simple electromagnet consists of 12 coils of magnetic wire wrapped around a rotor core. We used 23 gauge, single strand copper magnet wire with thin, enamel insulation. 46 turn every coil became a rotor core.
