Brushless DC motors have been around for many years but there has always been the need for a separate DC power supply. In applications using only an AC supply this introduced added cost and complexity. Then, in 2003, ebm-papst brought out an EC fan with integrated electronics which could be connected directly to an AC mains supply. In addition to performing the commutation, the electronics convert AC to DC and control the fan speed by regulating the power to the motor.
Put simply, DC motors are around 30% more efficient than AC motors because the secondary magnetic field comes from permanent magnets rather than copper windings. An AC motor consumes additional energy solely to create a magnetic field by inducing a current in the rotor. But this is only half the story. The use of modern electronics in controlling the motor has opened up many other possibilities which contribute to using less power.
Construction
Cowls are of galvanised steel construction.
Impellers are backward-curved centrifugal design and are of high performance composite material.
Bird-mesh guards are an optional extra.
Powder-coating is an optional extra.
Special Note
Backdraft shutters are an optional extra. The pressure loss across the shutter has to be added to the system pressure before making selections.
All GL Gamma EC models can be pre-configured to suit specific sensors and specific applications. Please advise Fantech of these parameters at the time of order.
EC motors should be directly connected to their appropriate AC supply. EC motors should not be regularly power cycled.
