1.2Solar Pumping Inverter:

The operation of the solar water pump is controlled and regulated.The pump is driven by the electric energy from the solar array,and the output frequency is adjusted instantly according to the change of sunshine intensity,so that the output power is close to the maximum power of the solar array.

1.3Pump:

Usually,lifting liquid,transporting liquid or increasing pressure of liquid,that is to say,turning the mechanical energy of the prime mover into liquid energy,so as to ahieve the purpose of pumping liquid machine is collectively called pump

Utilizing the power from solar cells,high-efficiency water pumps are driven by DC,payment magnet,brushless,postion sesor-less,stator rotor double plastic-encapsulated motor or high-speed switched reluctance motor through max power point tracking,conversion and controldeveices.Water is lifeted from the deep surface to the ground for framland irrigation or human and animal drinking.

3.1DC brushless solar water pump(motor type):

Brushless DC motor pump is composed of brushless DC motor and impeller.The shaft of the moter is connected with the impller.There is a gap between the stator and the rotor of the pump.Water will penetrate into the motor for a long time,which increases the possibility of motor burnout.
