Abstract: A method for locking the rotor of a wind turbine includes providing the rotor with at least one rotor blade which can be displaced about its longitudinal axis by an adjusting device from an operating position into a vane position, in which substantially no torque acts upon the rotor. The rotor drives a generator and can be prevented from rotation in a locking position by inserting a locking bolt into a rotor-side receiving opening. A wind turbine for performing the method includes a rotor which is induced into a creeping rotational movement at such a low rotational speed by short-circuiting at least one stator winding of the generator that a locking bolt can be inserted into a rotor-side receiving opening while the rotor is rotating.

Abstract: Disclosed is a generator for a wind energy installation having a rotor which has permanent magnets and is directly connected for drive purposes to a blade rotor of the wind energy installation, and having a stator which has an iron core composed of laminates. The generator is formed without the rotor or the stator on the external circumference as a completely surrounding housing, and the laminates of the stator are connected to one another by adhesive bonding and/or welding.
