Abstract
A method of forming a stator for an electric machine having a cascaded winding includes the steps of: providing a stator core having a plurality of circumferentially spaced and axially-extending core slots in a surface thereof, forming a plurality of A conductors and a plurality of B conductors, arranging the A and B conductors into a wire pack, rolling the wire pack into a cylindrical shape and inserting the wire pack within the stator core, and expanding the wire pack radially outward such that the wire pack is inserted within the slots of the stator core.
