Means to rotate the rotor of a wind turbine and method to rotate the rotor

摘要

The invention relates to means to rotate the rotor of a wind turbine and a method to rotate the rotor. A direct driven wind turbine comprises an electrical generator with a rotor and a stator, a hub constructed to receive a rotor blade, and actuator means, whereby the hub is connected to the rotor of the electrical generator. The hub and the rotor of the electrical generator are rotatable mounted to the stator of the generator. The actuator means are constructed and arranged to rotate the rotor of the electrical generator in respect to the stator of the electrical generator, whereby the actuator means comprise a linear actuator and the linear actuator rotates the rotor of the generator.
