Disadvantage: As long as the motor rotates, the carbon brush will wear out. When the water pump runs to a certain extent, the wear gap of the carbon brush will increase, and the sound will also increase. After running continuously for hundreds of hours, the carbon brush cannot play the role of reversing.

Advantages: Low price.

Working principle of brushless motor DC water pump

The motor type brushless DC water pump is composed of a brushless DC motor and an impeller. The shaft of the motor is connected to the impeller.

Disadvantage: There is a gap between the stator and rotor of the water pump, and if used for a long time, water will seep into the motor, making it easy for the motor to burn out.

Advantages: Brushless DC motors have been standardized and mass-produced by specialized manufacturers, resulting in lower costs and higher efficiency.
