Product Description

310mm DC BLDC 102mm Rotor Motor Backward Curved Centrifugal Fan for Cooler
Model:PB3N310B24H/PB3N310B48H

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.
