Abstract: A method of determining a readjustment value in position and/or in orientation of a stator segment of a multi segment stator of an electrical machine is provided, the stator segment to be assembled with a shaft, the method including: detecting positions of plural first reference objects attached to the stator segment using a camera system; detecting positions of plural second reference objects attached to the shaft using a laser tracking system; detecting positions of plural third reference objects attached to the camera system using the laser tracking system; determining the readjustment value in position and/or in orientation of the stator segment based on the positions of the plural first, second and third reference objects.

Abstract: A blade root cover segment suitable for fitting to a wind turbine blade to span a gap between the blade and a spinner cover. The blade root cover segment includes a first end and a second end and comprises: a curved flange for abutting against a correspondingly curved surface of the wind turbine blade; a cover wall extending radially from the flange; and a tensioning band associated with the flange. The tensioning band comprises a first end proximate to the first end of the blade root cover segment and a second end proximate to the second end of the blade root cover segment, and wherein the first end and the second end of the tensioning band include connection means for connecting with and applying tension between a like blade root collar segment. The invention also encompasses a blade root cover comprising a plurality of blade root cover segments. The invention also extends to a method of assembling a blade root cover from a plurality of blade root cover segments.
