Claim 0:
1. An assembly method for an electric machine of a wind turbine, comprising:
segmenting a stator of the electric machine into a plurality of stator segments in a circumferential direction, and segmenting a rotor of the electric machine into a plurality of rotor segments in the circumferential direction;
forming at least two segment modules by the plurality of stator segments and the plurality of rotor segments,
wherein each segment module comprises at least one stator segment and at least one rotor segment,
wherein the at least one stator segment and the at least one rotor segment of each segment module are fixed coaxially on a respective fixing device by fixing the at least one stator segment to one or more first fixtures of the respective fixing device and fixing the at least one rotor segment to one or more second fixtures of the respective fixing device to maintain a predetermined gap in a radial direction between the at least one stator segment and the at least one rotor segment,
wherein the respective fixing device comprises a base on which the one or more first fixtures and the one or more second fixtures are arranged, and
wherein the base comprises a positioning surface arranged parallel to a segmental end face of the at least one stator segment or the at least one rotor segment in the circumferential direction, the positioning surface is provided with an aligning device comprising an aligning shaft, and the aligning shaft of the respective fixing device is insertable into an aligning hole of an adjacent fixing device;

moving and adjusting respective fixing devices associated with the at least two segment modules, so that segmental end faces of stator segments and rotor segments of adjacent segment modules from the at least two segment modules in the circumferential direction are respectively attached to and aligned with each other;
assembling the at least two segment modules into the stator and the rotor in the circumferential direction, and then assembling a main shaft, the stator, and the rotor coaxially into an integral; and
dissembling the respective fixing devices associated with the at least two segment modules.
