Danotek today announced they will be expanding their portfolio with the addition of large PM generators for low- to medium-speed applications primarily intended to meet the growing market for offshore wind turbines with rated outputs within the range of 6 to 8MW.
CANTON , MI (September 27, 2011) ó Danotek, a leader in the development and manufacture of highly efficient and reliable permanent magnet (PM) generators and power converter systems for the global wind energy market, today announced they will be expanding their portfolio with the addition of large PM generators for low- to medium-speed applications primarily intended to meet the growing market for offshore wind turbines with rated outputs within the range of 6 to 8MW.
The offshore wind market has been steadily growing globally. From today's installed base of 4.1GW, offshore wind is forecast to grow at a CAGR of more than 60% to exceed 70GW by 2017 (Pike Research, 2011, Global Wind Energy Outlook Report). Growth in offshore wind is primarily driven by increasing demand in Europe and Asia. One of the challenges facing developers of offshore wind projects is the reliability of the wind turbine drivetrain. Traditional double-fed induction generators (DFIG) have the disadvantage of requiring extensive, and potentially expensive, routine servicing of the brush gear and slip-rings. PM generators completely avoid this maintenance headache.
"Danotek's decision to address the offshore market came very naturally," CEO Don Naab stated. "With all the attention and success we have had with our current permanent magnet generator onshore programs, our confidence and customers have driven us to this decision." Furthermore, in June 2011, a consortium led by the National Renewable Energy Laboratory (NREL) that includes Danotek, was one of six groups selected for an award by the Department of Energy (DOE) to advance next-generation designs for wind turbine drivetrains. The project will focus on reducing the cost of wind energy by optimization of the wind turbine drivetrain, with technology developed being scalable to drivetrains of 10MW or more. Commenting on the programs' synergies, Mr. Naab said "We anticipate leveraging knowledge gained from the DOE program to enhance and accelerate our 7MW offshore generator program."
