What are the differences between brushed solar pumps and brushless solar pumps?

Solar water pumps (also known as photovoltaic water pumps) are the most attractive water supply method in the sun-rich areas in the world today, especially in remote areas without electricity. The system uses the available and inexhaustible solar energy to fully automatically sunrise Rather, it stops at sunset and does not require personnel supervision, and the maintenance workload can be reduced to a minimum. It is an ideal green energy system integrating economy, reliability and environmental benefits.

Brush DC solar water pump:

When the water pump is working, the coil and commutator rotate, and the magnet and carbon brush do not rotate. The alternating current direction of the coil is completed by the commutator and brush as the motor rotates. As long as the motor rotates, the carbon brush will wear out. When the computer water pump runs to a certain extent, the carbon brush wear gap becomes larger, and the sound will increase accordingly. After hundreds of hours of continuous operation, the carbon brush can no longer play a role in commutation.

Advantages: low price.

Brushless DC solar water pump:

(Motor type):

The motor-type brushless DC pump is composed of a brushless DC motor and an impeller. The shaft of the motor is connected with the impeller, and there is a gap between the stator and the rotor of the water pump. If it is used for a long time, water will penetrate into the motor and increase the possibility of motor burnout.
