For several years, brushless DC motors have been used as drive motors in photovoltaic water pump systems. This is because this type of motor has high efficiency that is not easily achieved by ordinary AC motors. It is expected to reduce the relatively expensive solar The amount of battery used has significant economical benefits. However, since photovoltaic water pumps usually require the motor to run submerged in water.

The brushless DC water pump adopts electronic components for commutation, no need to use carbon brush for commutation, and adopts high-performance wear-resistant ceramic shaft and ceramic bushing. The bushing is integrated with the magnet through injection molding to avoid wear and tear. The life of the pump is greatly enhanced. The stator part and rotor part of the brushless peripheral solar pump are completely isolated, the stator and circuit board parts are potted with epoxy resin, 100% waterproof, the rotor part uses permanent magnets, and the pump body is made of environmentally friendly materials, with low noise and small size , stable performance. Various required parameters can be adjusted through the winding of the stator, and it can operate with a wide range of voltages.
