Abstract: A rotary electric machine includes a rotor, a stator having coils wound to surround the rotor, a cylindrical ring member fixedly mounted on the stator by shrinkage fitting, and a frame disposed on the outside of the ring member with a gap created in between. The distance of the gap varies as a result of thermal expansion of the stator and the ring member. An outer surface of the ring member goes into contact with the frame when the stator and the ring member thermally expand, whereby the stator and the ring member are efficiently cooled.

The generator includes a housing with a multi-piece stator arrangement mounted to the housing, the stator arrangement surrounding radially inward and radially outwardly directed faces of a rotor assembly, also surrounded by the housing. The rotor assembly is configured for direct attachment to a wind turbine main shaft so that rotation of the main shaft results in like rotation of the rotor assembly. The housing is mechanically coupled to the rotor by anti-friction elements such that the rotor is free to rotate about its central axis relative to the housing, and such that radial displacement of the rotor due to main shaft deflections results in a like radial displacement of the housing.
