Abstract:
1. A generator for a wind turbine, comprising: a housing defining a center axis; a stator arrangement mounted to interior surfaces of the housing and centered about the center axis; a rotor assembly configured for direct attachment to a wind turbine main shaft such that rotation of the wind turbine main shaft results in a like rotation of the rotor assembly, the rotor assembly having radially inward and radially outward directed faces, the radially inward and radially outward directed faces each facing a portion of the stator arrangement; and wherein the housing is mechanically coupled to the rotor assembly such that the rotor assembly is free to rotate relative to the housing and such that displacement of the rotor assembly from the center axis of the housing results in a like displacement of the stator arrangement and the housing.
