Wind turbine direct drive airgap control method and system

摘要

A deflection resistant wind turbine generator (100) having a stator (203) arranged about an axis and a rotor (201) operably mounted with respect to the stator (203) to generate electricity. The rotor (201) is rotatably communicating with wind turbine blades (108) rotating substantially about the axis and the rotor (201) and the stator (203) are configured to maintain an airgap (207) therebetween. The stator (203) and the rotor (201) have selectively engageable surfaces (211,213) that maintain a substantially stable airgap (207) and permit rotation of the rotor (201) during engagement. The engageable surfaces (211,213) engage when the rotor (201) deflects to a predetermined amount of deflection.
