BrightBlueJim states: June 18, 2019 at 8:forty eight pm And in many cases this leaves out the crucial big difference: BLDC motors are actually AC synchronous motors. All motors want some implies of producing a section distinction between the stator plus the rotor, so that there's a torque made. Brush-commutated DC motors and AC/DC common motors use carbon brushes and a segmented copper commutator To achieve this, and you'll find three undesirable repercussions: friction, don, and sounds. Don could be the most vital consequence, mainly because it implies that brush-commutated motors require periodic routine maintenance.
