140mm AC 220~ 230V External Rotor Motor Forward Curved Centrifugal
Fans with Plastic ImpellerModel:PF2K140B2AS/PF2K140B2ASS
/ Motor: External rotor AC motor 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. Product

Diagram7. Safety Requirements1. Make sure that the metal casing of
the stator connected to the ground before being powered on. 2. Fan
needs a few seconds to start after being powered on. To prevent
personal injury, do not touch the impellers or rotor when the power
is on or in a low speed. 3. Unless they are instructed by the
person(s) responsible for their safety, those who are lack of
physical, mental or sensory capacities and proper practical
experience or expertise cannot use this appliance. Please do not
let the children play with this product. 4. If the power cord be
damaged, the power cord must be replaced by the manufacturer in
order to avoid accident of the proxy service personnel or the
equivalent qualification maintenance personnel. 5. Please carefully
read this technical specification before using the product.
