Abstract
A method for producing a magnetically excitable core for an electrical machine, by which in a method step (S), the core, having a substantially parallelepiped shape with slots extending parallel on one side, is furnished, into whose slots, in a method step (S), the core winding is inserted by its winding sides, and then in a method step (S), the core together with the core winding is reshaped into a cylindrical ring shape with radially inward-oriented slots, is proposed. The method is characterized by a further step, according to which in each case all winding sides that are inserted into each slot are pressed into a slot shape in a tool and reshaped before being inserted into the slot.
