Brushed DC solar water pump:
When the pump is working, the coil and the commutator rotate, the magnetic steel and the carbon brush do not rotate, and the alternating current direction of the coil is completed by the commutator and the brush that the motor rotates, as long as the motor rotates the carbon brush, the wear occurs. When the computer water pump runs to a certain extent, the carbon brush wear gap becomes larger and the sound will increase accordingly. After several hundred hours of continuous operation, the carbon brush cannot play the role of reversing.
