Improve customer return on investment The traditional AC motor only get maximum speed is 2850RPM,and it only could passively discharge according the voltage,not according power. efficiency will low.Question:Why Liyuan solar pump use shield motorAnswer:shield design make the mechanical seal is unnecessary, avoiding the risk of mechanical seal leakage because of mechanical seal wear and tear. Avoiding the reduce of efficiency because of mechanical seal friction also ,at the same time ,wet rotor cooling better.Question:Why Liyuan solar pump use Permanent Magnet motor not AC motorAnswer:Our magnetic field of permanent magnet motor is provided by permanent magnet themself (rare earth) ,have not any lose of efficiencyWhile traditional AC motors magnetic field is provided by rotation of rotor and stator.so part of input power be used to generate magnetic field,reduces efficiencyQuestion:Why Liyuan solar pump use BLDC motor not brush DC motorAnswer:Although brushed DC motor can work directly with solar panels also, it's not good option,there have follow different from BLDCLife BLDC motor is 10000H,while brush pump Maximum life is 2000h~3000H because the brush and slip wear and tear.DC brush pump system has very low efficiency without MPPT. There isn't any Protection because of without controller also, too noise. Safety is significantly lower than BLDC motor.    Factory InformationGuangdong Jiangmen Liyuan Pump Co., Ltd. has started its production of submersible water pumps since 29 years ago.
