Abstract
Provided is a method of manufacturing a stator or a rotor of an electrical machine, the steps of: modelling a plurality of model segments circumferentially joined together in such a way that two circumferentially adjacent model segments contacts each other at respective circumferential interfaces, the plurality of model segments including a plurality of model teeth interposed between a plurality of slots, manufacturing the segmented body in such a way that at least the two end slots are circumferentially shifted away from the circumferential interfaces of the respective model segment for creating respective gap portions of the circumferential gap, the sum of the circumferentially shifts of the at least two end slots being equal to the sum of the circumferential extensions of the gap portions, circumferentially joining the plurality of segments together in such a way that two gap portions of two adjacent segments forms the respective circumferential gap.
