AMSC, through its Windtec subsidiary, jointly developed the doubly fed induction turbine, known as the SL5000, with Sinovel, which became the third largest wind turbine manufacturer in 2009 by market share.
Sinovel is one of AMSC’s most important customers. Last year, the Massachusetts-based company supplied Sinovel with about 3.9 gigawatts of electrical components for the 2,400 1.5MW and 100 3MW turbines it shipped.
AMSC says it intends to deliver the 5MW electrical control systems to Sinovel in the second half of this year.
