Wind turbine gearbox replacement cost can be as much as US$350,000. But EPRI’s physics-based AI early damage detection model, tested on WEC Energy Group, Southern Company and other utility’s wind ...

Wind turbines last longer than ever thanks to continuous engineering improvements. Gearboxes in wind turbines, more than those in any other application, tend to fail prematurely. In fact, at some wind ...

Gearboxes in general are a result of over 80 years of accumulated engineering knowledge. So why do gearboxes for wind turbines sometimes fail after seven to 11 years — way less than the anticipated 20 ...

Wind turbine gearboxes have been designed with a life-expectancy of 20 years, but the harsh reality is that they are not lasting for a quarter of that time, says Leyla Alieva, CEO and co-founder, NEOL ...

A distinct trend is emerging in the manufacture of wind turbine generators-the use of permanent magnets (PM). At the American Wind Energy Association’s Global Windpower 2007 Conference and Exhibition ...

A planned supersized floating wind turbine with two spinning heads will generate nearly double the amount of energy as the ...

Six Northern Power 100 kW direct drive wind turbines produce power for Unalakleet, Alaska. The turbines are owned by Unalakleet Valley Electric Cooperative. Photo courtesy STG Inc. For years, wind ...

This file type includes high resolution graphics and schematics when applicable. The simplest axial magnetic gearboxes consist of two disks each containing alternating positive and negative magnets ...

More than 1,200MW of wind power capacity was installed in the United States in the third quarter of 2011 alone, bringing new installations through the first three quarters of the year to 3,360MW, ...
