Abstract
An installation system and a method for mounting a rotor blade to a hub on a wind turbine are disclosed. The method includes coupling a rotor and a stator together, the rotor rotatably connected to the hub. The method further includes rotating the stator in a first direction, wherein rotation of the stator causes the rotor and the hub to rotate in the first direction. The method further includes securing the hub to prevent rotation of the hub. The installation system includes a coupling device configured to releasably couple a stator and a rotor together and a securing device configured to releasably secure the hub. The installation system further includes at least one stator drive device operably connected to the stator, the stator drive device configured to rotate the stator between a first position and a second position.
