• Note: very mini!
• The rusty or damaged motor on the machine can be replaced.
• Easy to disassemble and maintain, suitable for mini fans, scientific experiments, remote control toy car robots, etc.

Note: very mini! Note: when the carbon brush head sticks to the rotor's commutator head, it cannot be completely stuck at the beginning, leaving a gap. But when the brush is rubbed after rotation, the brush will be completely attached to the commutator head. This is simple anti-physics. Years of practice.
