Patent ID: 7154192

Claim:
A wind turbine comprising: a direct drive wind turbine generator, the generator comprising: at least one rotor comprising an inner rotor core comprising at least one first permanent magnet and an outer rotor core comprising at least one second permanent magnet, wherein the outer rotor core is inverted with respect to the inner rotor core; and at least one double-sided stator comprising an inner stator side including an inner stator winding disposed about one side of a double-sided lamination stack, an outer stator side including an outer stator winding disposed about an opposing side of the doublesided lamination stack, wherein the at least one double-sided stator is disposed concentrically between the inner rotor core and the outer rotor core and is configured to enable at least a portion of magnetic flux to be shared between the inner stator side and the outer stator side and wherein the at least one rotor and at least one double-sided stator cooperate to produce at least 2.0 megawatts of power.
