EC DC input ec centrifugal exhaust fan
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.
Fresh Air System Extractor Fan With Energy Saving/ Save Electricity
1． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation
2． Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer
Fresh Air System Ec Centrifugal Fan With New Energy For Ld280c-230d3-01
1． Brushless DC external rotor motor belongs to non-mechanical brush(commutator)DC motor which enforces the winding current commutation through electronic commutator (position sensing, non- position sensing),achieve the speed control function with PAM or PWM control
2． Enable the selection of different power levels thus to get the best match of price and performance according to customers’load requirements
