What are the working principles of brushless solar water pumps?

Brushless DC solar water pump (motor type)

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. There is a gap between the stator and the rotor of the water pump. As the water is used for a long time, water will penetrate into the motor, increasing the possibility of the motor burning out.

Brushless DC magnetic isolated solar water pump

Brushless DC water pump uses electronic component commutation, no carbon brush commutation is needed, high-performance wear-resistant ceramic shaft and ceramic bushing are used, and the bushing is integrated with the magnet through injection molding to avoid wear and tear, so brushless DC magnetic force The life of the water pump has been greatly enhanced. The stator and rotor parts of the magnetically isolated water pump are completely isolated. The stator and circuit board parts are encapsulated with epoxy resin and 100% waterproof. The rotor part is made of permanent magnets. The pump body is made of environmentally friendly materials, with low noise, small size and performance. stable. Various required parameters can be adjusted through the windings of the stator, allowing wide voltage operation.
