Title:
WIND TURBINE GENERATOR WITH LOCALIZED AIR GAP CONTROL AND A WIND TURBINE HAVING SUCH A GENERATOR
Document Type and Number:
WIPO Patent Application WO/2012/159108
Kind Code:
A3
Abstract:
A wind turbine component (18) includes an inner member (32) and an outer member (34) disposed relative to the inner member (32), wherein the inner and outer members (32, 34) move relative to each other. A plain bearing (200) is coupled to one of the inner or outer member (32, 34) and configured to provide a fluid film (202) for maintaining separation of and facilitating relative movement between the inner and outer members (32, 34). A position adjustment mechanism (78) is coupled to the one of the inner or outer member (32, 34) for selectively moving the plain bearing (200). A position controller (176) may be operatively coupled to the position adjustment mechanism (78) for controlling the position of the plain bearing (200). The wind turbine component may be a wind turbine generator (18) with the inner member and outer member corresponding to one of the stator and rotor assemblies (32, 34). Methods for controlling the generator are also disclosed.
