Patent ID: 7726005

Claim:
A method of making an electromagnetically excitable core of an electrical machine with a multiphase winding ( 13 ), said method comprising: a) preparing core ( 10 ) having a substantially parallelepiped shape; which is provided with a plurality of parallel grooves (N 1 to N 36 ; N 1 to N 48 ) in one side in a first method step; and b) in at least one subsequent method step at least three phase windings ( 100 , 200 , 300 ) are laid in said grooves of said core ( 10 ) in such manner that only one winding overhang is outside of said core, while other of said at least three phase windings do not have a winding overhang, wherein first coil sides of one phase winding are laid in one groove and a part of other coil sides of a first coil of another phase winding are laid in another groove, which is displaced electrically by 60 degrees from said one groove, so that said part of said other coil sides of said first coil form a first physical end of said another phase winding, and a remaining part of said other coil sides of said first coil of said another phase winding are also laid in said another groove but said remaining part of said other coil sides of said first coil form a second physical end of said another phase winding.
