Brushless motor
The working principle of a brushless motor can still be imagined as a cylinder, but this time it is not a small round rod rotating in the middle, but a piece of magnet rotating in the middle. The column wall is not the two magnetic poles of the magnet, but the "fan blades" that were just electrified. In this way, as long as electricity is applied, the column wall has a magnetic pole due to electromagnetism, which generates mutual repulsion with the middle magnetite. Then the magnetite rotates wildly, and the electrical energy is converted into kinetic energy. The biggest difference between it and a brushed motor is that there is no need to power on those two brushes, because we can directly power on the column wall. The benefits of this are very obvious because there is no friction between the brushes, so the speed is faster, the loss is reduced, the output power is greater, the lifespan of the motor is longer, and it does not produce sparks. This is simply good news for some electrical appliances in flammable locations.
