Abrushless DC pumpis a water pump driven by a brushless direct-current motor. It replaces carbon brushes found in older DC designs with electronic switching, so the rotor turns with almost no friction. Fewer rubbing parts cut wear, lower noise, and extend bearing life.

Der Controller sendet schnelle elektrische Impulse an die Statorspulen. Diese Impulse erzeugen ein bewegliches Magnetfeld, das die am Rotor befestigten Permanentmagnete anzieht. Da das Schaltmuster softwaregesteuert ist, kann der Motor seine Drehzahl schnell ändern. Dadurch kann die Pumpe den Durchfluss an den Bedarf anpassen, anstatt Energie durch Drosselventile zu verschwenden.

Inside the hydraulic end, a centrifugal orscrew impellermounts on the same shaft. When the motor spins, the impeller scoops water and pushes it up the discharge pipe. Brushless efficiency often reaches ninety percent, so more of each watt becomes useful lift. Soft-start logic also avoids high inrush current, protecting cables and solar panels.

SAMKING Pump uses brushless motors from 300 W to 20 kW in bothsurface and submersiblebodies. Users can select plastic or SS304 impellers, built-in or external controllers, and optional GPRS links for remote wells. The design suits solar arrays because no inverter stage is needed.
