The main difference between DC brushless water pump and brush water pump lies in their different motor structures and control methods. Brush water pumps use motors with carbon brushes, which require regular brush changes, as well as sparking and noise problems due to friction, while brushless water pumps are controlled by electronic controllers without carbon brushes, and have the advantages of low noise, longevity and high efficiency.

Compared with DC brushless water pump and brushless water pump, brushless water pump has the following advantages:

1, low noise: no motor using PWM technology to control the motor speed stability, low noise

2, high efficiency: brushless electric in the winding without brush friction loss, high motor efficiency

3, long service life brushless motor in the brush, there is no brush wear problem, long life.

4, stability: the use of digital control technology, high precision control, stable motor operation.

In contrast, there are disadvantages of brushed pumps:

1, noise: friction between carbon brushes and rotating parts will produce noise.

2, low efficiency: due to the existence of brushes, motor efficiency is not as good as brushless motor.

3, short life: brush wear leads to a short life.

4, poor stability: easy to run unstable due to brush wear and other problems.

Brushless water pump stator winding:

Brushless water pump stator is mostly 6 slots, common fish tank small water pump, submersible pump, and car water pump, etc. The slot inward stator generally uses needle winding machine, according to the various parameters of the stator, you can use double station, four station or six station equipment; slot outward, such as car water pump stator, more than the use of special flying fork winding machine equipment. The quality of winding needs to be determined according to the stator product and the equipment, the higher the precision the better the quality of winding.
