5.Outline Drawing

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.
