First Claim
1. A wind turbine generator having a drive end at which one or more turbine blades are mountable and a non-drive end, the wind turbine generator comprising:
- —
a first substantially cylindrical hollow body having a radially inner surface;
a second substantially cylindrical hollow body located within the first substantially cylindrical hollow body and having a radially outer surface;
one of the first substantially cylindrical hollow body and the second substantially cylindrical hollow body being a rotor;
the other of the first substantially cylindrical hollow body and the second substantially cylindrical hollow body being a stator, an air gap being defined between the rotor and the stator;
a main bearing arrangement at the drive end acting between the rotor and the stator to mount the rotor for rotation about the stator;
a stabiliser bearing at the non-drive end acting between the rotor and the stator to stabilise the rotor and stator and maintain the air gap therebetween.

Abstract
A wind turbine generator has a drive end at which one or more turbine blades are mountable and a non-drive end. The wind turbine generator comprises an external stator having a radially inner surface and an internal rotor having a radially outer surface, an air gap being defined between the rotor and the stator. A main bearing arrangement is provided at the drive end and acts between the rotor and the stator to mount the rotor for rotation about the stator and a stabiliser bearing is provided at the non-drive end and acts between the rotor and the stator to stabilise the rotor and stator and maintain and control the air gap therebetween.
