FAQ

Question:Why Samking solar pump use frequency converter

Answer :Variable frequency motor will actively change their speed according the all time changing power which provided by solar panels ,Perfect combination with MPPT, ultra-frequency operation, make sure absorb above 95% power provided by panels. 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 Samking solar pump use shield motor

Answer: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 Samking solar pump use Permanent Magnet motor not AC motor

Answer:Our magnetic field of permanent magnet motor is provided by permanent magnet themself (rare earth) have not any lose of efficiency

While traditional AC motor's magnetic field is provided by rotation of rotor and stator,so part of input

power be used to generate magnetic field,reduces efficiency

Question:Why Samking solar pump use BLDC motor not brush DC motor

Answer:Although brushed DC motor can work directly with solar panels also, it's not good option, there have follow different from BLDC

Life 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.
