Abstract

An improved BLDC water pump rotor comprising of Housing having magnets attached at one end of the housing surface and the extension of the Guiding pin and integrally formed with the housing surface of the extension portion a Rotor Assembly with Top Bush; and Bottom Bush; wherein, the Bottom Bush and Top Bush are lined with friction reducing material, that forms the area around the Guiding Pin with ultra high wearing resistant materials to minimize attrition on shaft; and enhancing the space between the Guiding Pin and Rotor Assembly to avoid contact. The improved BLDC water pump has up to 60% less wear and tear rate, increases 66% reliability and is up to 30 % cheaper in terms of cost as opposed to the conventional BLDC water pump.
