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