Abstract
The method of making a two-layer lap winding () for a multiphase electrical machine includes the steps of winding a first coil unit () of a first phase winding () around a winding bar (); subsequently laying a coil connector () of the first phase winding () in a first direction and then winding at least one other coil unit () of at least one other phase winding () around the winding bar () and over the coil connector (). Subsequently a second coil unit () of the first phase winding () is wound around the winding bar () following all first coil units of all phase windings and after all coil connectors from the first coil units are laid. A method of making a stator from the two-layer lap winding () is also described.
