What is a brushless motor?
In: Engineering
A brushless motor speed control has smart electronics that can figure out in what position the rotor with the magnets is at any time.
It switches the copper coils that surround the rotor on and off hundreds or even thousands of times per second so that the magnetic field that the coils create is always “ahead” of the magnets of the rotor. That way they keep dragging/ turning the rotor magnets in one direction.
brushless motors are vastly more efficient than brushed motors, they can be much more powerful and they dont have any parts that wear out, apart from the bearings. The big disadvantage is that they rely on an electronic speed control to function.
