Explanation:
A brushed DC motor uses a configuration of wound wire coils, the armature, acting as a two-pole electromagnet. The current's directionality is reversed twice per cycle by the commutator, a mechanical rotary switch. ... A brushless motor, by contrast, utilizes a permanent magnet as its external rotor.
