METHOD TO ROTATE THE ROTOR OF A WIND TURBINE AND MEANS TO USE IN THIS METHOD

摘要

A direct driven wind turbine includes an electrical generator with a rotor and a stator, a hub constructed to receive a rotor blade, and an actuator device. The hub is connected to the rotor of the electrical generator. The hub and the rotor of the electrical generator are rotatable mounted in respect to the stator of the generator. The actuator device is constructed and arranged to rotate the rotor of the electrical generator and the hub of the wind turbine in respect to the stator of the electrical generator, wherein the actuator device is at least one motor.
