Wind turbine generator with localized air gap control and a wind turbine having such a generator

A wind turbine having a wind turbine component, the wind turbine component comprising:

• an inner member;
• an outer member disposed relative to the inner member,
• the inner and outer members moving relative to each other, and one of the inner or outer members including a plurality of member segments each including:
• a plain bearing coupled to the member segment and configured to provide a fluid film for maintaining separation of and facilitating relative movement between the inner and outer members, the plain bearing establishing an adjustable air gap between the member segment and the other of the inner or outer members, and
• a position adjustment mechanism including an actuator coupled to the member segment for selectively moving the plain bearing;
• and
• a position controller operatively coupled to the actuator of the position adjustment mechanism of at least one member segment and configured to:
• monitor a parameter, and
• actuate the actuator so that the position adjustment mechanism positions the plain bearing of the at least one member segment to control the adjustable air gap between the at least one member segment and the other of the inner or outer members based on the monitored parameter.
