Patent number: 7449794Abstract: A wind turbine with a self-contained power system is disclosed. The self-contained power system comprises an auxiliary generator with a winding disposed on the rotor side while the magnetic poles of the auxiliary generator are disposed at components moving relatively to the rotation of the rotor. Thereby, a back electromotive force (emf) is generated in the winding due to the relative motion of the winding with respect to the magnetic poles as the rotor is rotating, and consequently the self-contained power system generates electricity to provide the power for driving the rotor to rotate. Therefore, the ability of the wind turbine to operate independently is enhanced since the amount of back-up power supply required is reduced and the structure of the wind turbine is simplified. Therefore the cost of the wind turbine is reduced, and the system reliability is increased.Type: GrantFiled: August 14, 2007Date of Patent: November 11, 2008Assignee: Industrial Technology Research InstituteInventors: Zen-Jey Guey, Yun-Yuan Chang, Ching-Huei Wu
