Method for assembling a segmented electrical machine while maintaining gaps between segments

摘要

In a method an inner segment is first pre-assembled on each of a number of outer segments by at least one fixing element, so as to produce a plurality of segment modules having each a predetermined air gap between the inner segment and the outer segment. The inner segments and the outer segments are assigned to the rotor or stator of the electrical machine. The inner segments of the plurality of segment modules are fastened to an inner assembly device (for example a hub). The outer segments of the plurality of segment modules are fastened to an outer assembly device (for example a supporting structure). Finally, the fixing elements between the inner segments and the outer segments are removed.

1. A method for assembling an electric machine, comprising:
pair-wise mounting an inner ring segment on an outer ring segment by at least one fixing element to thereby produce multiple segment modules, each having a predefined air gap between the inner and outer ring segments; fixing the inner ring segments of the segment modules on an inner assembly device to form a complete ring; fixing the outer segments of the segment modules on an outer assembly device, wherein the segment modules are fixed to the inner and outer assembly devices in such a way that a gap remains between neighboring ones of the segment modules in a circumferential direction; removing the fixing elements between the inner and outer segments of the segment modules; and inserting a connecting element in the gap to connect the neighboring segments modules with one another.
