Abstract
A method () is described for making a stator () of an electric machine, the stator comprising a stator core (), the stator core comprising a main body and a plurality of slots () which are axially extended inside the main body and are adapted to receive bar conductors. (5, 5', 5″) of a bar stator winding. The method () comprises the steps of : inserting () at least one preshaped insulating sheet () inside at least one of said slots (); hot shaping () said preshaped insulating sheet () inside the slot, along the entire axial extension of the slot () or along a substantial portion thereof, in order to confer form regularity and stability to said preshaped insulating sheet (). Through the described process, it is possible to make stators with bar winding having a stator core with relatively high height and slot fill factor.
