motors are also known as Electronically Commutated (EC) motors and consist of a motor combined with an inverter. The BLDC motor has a rotor that is a permanent magnet, the magnetic field of which interacts with the rotating magnetic field produced by the stator windings. This is combined with an electronic commutation system that is made up of an
