Highway DC Plastic Impeller Centrifugal Fan 250mm with EC Motor
Model:PB3N250B24H / PB3N250B48H
PBM Motor and Fan is a China mainland manufacturer and EC technology consulting company offering an extensive range of EC(Electronically Commutated) motors, fans and solutions, investing in the latest developing, manufacturing and technical equipment with in-depth processes & procedures. Our main products are EC fans, including EC axial fans, EC centrifugal fans and EC blowers. We do both AC and DC current type. And EC Motor is the core technology of our products.
Eletronically Commutated Motors(EC Motors)also known as Brushless DC Motors(BLDC) are synchronous electric motors powered by direct-current(DC) electricity and having electronic commutation systems,rather than mechanical commutators and brushes.The current-to-torque and voltage-to-speed relationships of BLDC motors are linear.
PBM fans are widely used in many fields. For example, axial fan for telecom, backward curved centrifugal fan for air exchanger,(inline duct fan)hydroponic products and FFU, forward curved centrifugal fan for air purifier and air conditioning,blower for kitchen.
