Excellence in Micro pump, DC pump Brushless DC Magnetic Pump VS Traditional Brush Pump Through magnetic drive technology, brushless magnetic pump realized non- contact torque transmission, thus displacing dynamic sealing by static sealing, which successfully solves the leakage problem, eliminates potential safety risk of inflammable & explosive & poisonous liquid leakage, and effectively guarantees the safety production and workers' health. How brushless DC pump works? Firstly, we should have an overview about the structure of brushless DC Magnetic pump. Unlike the brush pump, brushless pump is driven by magnetism. The impeller and permanent magnet are molding from one complete injection mold, which makes up the pump rotor. The high-performance ceramic shaft is fixed in the pump housing through the rotor. Between stator and rotor, there is a thin layer of So there is no traditional mechanical shaft seal, and the whole pump is completely Water Outlet Pump Head Water Inlet Pump Chamber Lead Wire Excellence in Micro pump, DC pump TOPS Micro Pump & Motor Technology Co.,Ltd E-mail:[email protected], Web:www.topsflo.com

When the stator coils energize with electricity, magnetic field comes over and it drives permanent magnets rotor to run. After magnetizing, there will be an intact coupling magnetic system. The magnetic energy will reach the minimum when magnetic pole of stator coils is in opposite to magnetic pole of rotor, that is, the displacement angle of two magnetic poles O=0. And it will reach the maximum when magnetic pole of stator coils is the same polar with magnetic pole of rotor, that is, the displacement angle of two magnetic poles 0=2Tr/n. Removing the external forces, due to the magnet poles mutually...

Advantages compared with brush motor 1. Leak-tightness: Pump shaft adopts closed static sealing instead of dynamic sealing; pump stator and rotor are completely isolated from each other; and epoxy resin is poured between stator and circuit board. These design let the pump completely avoid media leakage. Submersible also can be customized, which will 2. Low energy consumption: Brushless motor is lower power consumption and high efficiency. Without independent lubrication and cooling water, it reduces energy consumption. 3. Long life span: Brushless motor adopts electronic components for reversing,...
