Tamiya Mini 4WD Motor Break in (Brush Motor) (forbidden technique) (not really)

^^^Sorry for the voice over, not the best since it’s my first time doing voice overlay on a video
*Why do we break in motors? The commutators are shaped like squares and the armature are cylindrical, so to break it in, we basically run it (with load or without load) so the comms can ”shave” itself to the cylindrical shape of the arms.

Lots of technique out there.
Breaking in a brushed motor using the water immersion technique, it helps in keeping those metal/carbon shavings building up on the arms plus the water keeps the motor in a manageable temperature minimizing thermal damage to the wires (if there’s any) it’s a little bit messy but it pays off in the end.
