Stator for an electrical machine

A multipole stator for an electric machine having a stator housing, a plurality of poles disconnectably attached to an inner side of the stator housing and a compound excitation winding, said excitation winding comprising a series of main winding elements each having a central opening, and a series of shunt winding elements arranged in said central openings;

• all shunt winding elements being wound from a continuous insulated wire onto assigned winding formers integrally connected with a band-shaped support of a flexible insulating material;
• each of said winding formers surrounding an opening in said band-shaped support;
• a longitudinal edge of said band-shaped support being formed with a plurality of wedge-shaped notches for anchoring said continuous insulated wire between respective shunt winding elements;
• two contact tabs attached to end portions of said longitudinal edge to provide connections to a negative and positive voltage respectively, ends of said continuous insulated wire being welded to said contact tabs;
• said band-shaped support being arched and arranged in said stator housing;
• and said poles passing through assigned openings in said band-shaped support.
