The first W22 high efficiency motors supplied by WEG in Europe have been installed on a green production plant producing sustainable bio-fuels.
Three 200kW four-pole 315L frame W22 motors were supplied to BioWanze in Belgium, with inverters, to drive a mill that processes wheat and beet syrup producing bio-ethanol – eventually enough to provide half the bio-fuel consumption in Belgium.
The BioWanze plant is capable of producing 758m3 of ethanol per day through a biomass boiler built for enhanced thermal efficiency. WEG's high efficiency motors were installed on the cooling tower under contract to Hamon Thermal Europe, a cooling tower manufacturer, and subcontractor to De Smet Engineering.
BioWanze says they were selected for their ability to reduce motor losses by 10—40%, compared to traditional ac induction motors, and for .their low noise and vibration characteristics – mostly due to their aerodynamic frame, which increases air flow and reduces overall temperature and hot spots.
They also feature a new WSeal system, which uses a W-ring with a metal cover to protect the rubber sealing from ultraviolet light, while also protecting against ingress of water and dust – so preventing damage to rolling bearings.
WEG's new motors also comply with (and in some cases exceed) the requirements of IEC60034-30, the harmonised IE (International Efficiency) grading standard, which will be standard worldwide from June 2011.
