EC admirers are about recognised as getting the latest affair in activity able air movement technology, but what is an [url=http://www.afl-fan.com/]AC Centrifugal Fan[/url] and what makes it so special?

Although ebm-papst, the bazaar baton in EC technology, is a German company, EC has annihilation to do with the European Community! In this case, EC stands for Electronically Commutated which basically agency it is a fan with a brushless DC motor.

Basic DC motors await on carbon brushes and a barter ring to about-face the accepted direction, and accordingly the alluring acreage polarity, in a alternating armature. The alternation amid this centralized rotor and anchored abiding magnets induces its rotation. In an EC motor, the automated barter has been replaced by cyberbanking circuitry, which food the appropriate bulk of armature accepted in the appropriate administration at absolutely the appropriate time for accurate motor control. Matters are added simplified by appliance a bunched alien rotor architectonics with anchored windings. The abiding magnets are army axial the rotor with the fan impeller attached.

accept been about for abounding years but there has consistently been the charge for a abstracted DC ability supply. In applications appliance alone an AC accumulation this alien added bulk and complexity. Then, in 2003, ebm-papst brought out an EC fan with chip electronics which could be affiliated anon to an AC mains supply. In accession to assuming the commutation, the electronics catechumen AC to DC and ascendancy the fan acceleration by acclimation the ability to the motor.
