Features
l Brushless, permanent magnetic rotor, maintenance-free, long life
l small size, high efficiency, low consumption, low noise
l Ceramic sleeve and ceramic shaft [optional]
l Stator and circuit board sealed by epoxy resin, completely water proof
l Parameter adjustable, 12v pump's head can be 1.5m to 3.5m..
l Can be customized
Difference between 2-phase and 3-phase sensor less BLDC pump
| 2-Phase | u Drived by sensor which should be put inside the pump body |
|
3-Phase |
u Drived by program, sensor less, whole control circuit can be put outside u Speed adjustable by PWM, analog signals(0-5v) or potentiometer[optional] u Locked-rotor and reverse connection protection u Automatic overload protection and over-temperature protection u Soft start with low in-rush current, great for PV panel |
