A wind turbine generator includes at least one rotating member, at least one stationary member, and a clearance gap control system. The stationary member is positioned such that a clearance gap is defined between a portion of the rotating member and a portion of the stationary member. The clearance gap is configured to facilitate transmitting a controllable magnetic flux therethrough. The control system includes at least one clearance gap measurement assembly, at least one power converter, and at least one controller. The controller is coupled in electronic data communication with the assembly and the converter and is configured to modulate a dimension of the gap by modulating the flux.
