Patent ID: 7302749

Claim:
A method of making a two-layer lap winding ( 12 ) for a multiphase electrical machine from a wire bundle ( 33 ), said method comprising the steps of: a) winding a first coil unit ( 20 ) of a first phase winding ( 14 ) around a winding bar ( 10 ); b) subsequently laying a coil connector ( 18 ) of the first phase winding ( 14 ) in a first direction; c) winding at least one other first coil unit ( 20 ) of at least one other phase winding ( 14 ) around the winding bar ( 10 ) and over the coil connector ( 18 ); d) laying at least one other coil connector ( 18 ) extending from said at least one other first coil unit ( 20 ) of said at least one other phase winding ( 14 ) in said first direction, so that after the winding of said first coil unit and said at least one other first coil unit, said coil connector and said at least one other coil connector extend to respective starting positions (A 1 , A 2 , A 3 ) of corresponding second coil units ( 22 ) of said first phase winding and said at least one other phase winding; and e) winding a second coil unit ( 22 ) of the first phase winding ( 14 ) around the winding bar ( 10 ) at a starting location (A 1 ) for said second coil unit ( 22 ) after all coil connectors ( 18 ) of said first coil units ( 20 ) of all of said phase windings are laid.
