IN-SLOT STATOR WINDING COMPACTION

摘要

A method of manufacturing a stator assembly for an electrical machine, including the steps of: arranging a plurality of elongate wire segments in single file along the depth of a stator slot located between opposing walls of a pair of adjacent stator core teeth; compressing the wire segments substantially in a direction of the stator slot depth, whereby the wire segments are compacted into the stator slot; plastically deforming at least one of the wire segments, whereby a cross-section of the plastically deformed wire segment is expanded in a direction along which the opposing tooth walls are spaced from each other; and deforming the tip of at least one of the pair of adjacent stator core teeth to at least partially close up the stator slot upon the compressed wire segments and further compacting the wire segments into the stator slot.
