“This is the largest medium voltage inverter ever manufactured by WEG. Our range, which previously extended to 4000-HP, has now doubled in a stroketo 8000- HP,” said Joable Andrade Alves of WEG, who worked in the development of the inverter, and is part of WEG’s International Sales team.“The99% efficiency and 22- year MTBF make this an outstanding product; it offers the highest efficiency and is the most reliable medium voltage inverter in the world.”
“It’s important to note that 99% of efficiency is an average 1% more efficiency than that delivered by any other medium voltage inverter on the market - and this can mean an economy of up to US$ 50,000,00 per year”, says Charles Schuh, Product Manager at WEG’s branch in the US.
With the development of the new MVW-01 to 8000HP, WEG has become the only Brazilian company capable of producing and testing equipment with this power range. The tests, essential to assure the equipment will support the real loadduring operation, have never been performed before, due to their complexity, risk and high cost. “We have made substantial investments in the construction of a new laboratory, and in expanding the dynamometer in our testing area, making us the only company in Brazil able to offer this kind of service”, said Joable Andrade Alves.
The MVW-01 inverter technology integrates state-of-the-art and highly reliable components, such as HV-IGBTs, which are also used on high speed trains in Europe. This technology allows the inverter to be used in the most demanding applications, such as the mining, cement, shipping, iron metallurgy and petro-chemical industries.
Produced at the WEG inverter plant in Jaraguá do Sul, state of Santa Catarina, the equipment will start operation at Weir Pumps in April of 2010. The motor was supplied through Motion Industries, WEG distributor in the US.
