BrightBlueJim suggests: June eighteen, 2019 at eight:forty eight pm And even this leaves out the critical change: BLDC motors are really AC synchronous motors.

Brush-commutated DC motors and AC/DC universal motors use carbon brushes as well as a segmented copper commutator To do that, and you'll find 3 undesirable implications: friction, dress in, and noise. Put on will be the most significant consequence, mainly because it ensures that brush-commutated motors want periodic upkeep.
