Patent ID: 7600311

Claim:
A method for producing a magnetically excitable core ( 24 ) having a core winding ( 40 ) for an electrical machine, by which in a method step (S 1 ), the core ( 24 ), having a substantially parallelepipiped shape ( 20 ) with slots ( 32 ) extending parallel on one side, is furnished, into whose slots ( 32 ), in a method step (S 2 ), the core winding ( 40 ) is inserted by winding sides ( 36 ), and then in a method step (S 3 ), the core ( 24 ) together with the core winding ( 40 ) is reshaped into a cylindrical ring shape with radially inward-oriented slots ( 32 ), wherein in each case all the winding sides ( 36 ) that are inserted into each slot ( 32 ) are pressed into a slot shape ( 119 ) in a tool ( 44 ) and reshaped before being inserted into the slot ( 32 ), characterized in that the winding sides ( 36 ) of the core winding ( 40 ) are pressed into the slot shape ( 119 ), which corresponds to a cross-sectional shape of the slots ( 32 ) of the core ( 24 ), minus at least a fraction of a thickness (d ISO ) of an insulating layer ( 123 ).
