Abrégé

The invention relates to a face commutator (101) having a supporting body (102) consisting of an electrically insulating material, a large number of connection segments (108) consisting of an electrically conductive material for connecting in each case at least one end of a coil winding, and a large number of contact surface segments (112) which form a contact surface (14) of the face commutator (101), the contact surface segments (112) being mechanically rigidly and electrically conductively connected to the connection segments (108), and the supporting body (102) and/or the connection segments (108) having an integral design, and the supporting body (102) being prefabricated and having openings (118) into which the connection segments (108) are inserted, characterized in that the supporting body (102), at least in sections, is overdimensioned in the region of the openings (118) in relation to the inserted connection segments (108), in that the connection segments (108) are fixed owing to a clamping effect of the supporting body (102), and in that the clamping effect is brought about by the overdimensioning, at least in sections, of the supporting body (102) in relation to the connection segment (108), as well as to a method for producing a face commutator.

Abrégé

The invention relates to a flat commutator (101) comprising a support body (102) that consists of an electrically insulating material, a large number of connecting segments (108) consisting of an electrically conductive material for connecting at least one respective end of a coil winding and a large number of bearing surface segments (112), which form a bearing surface (14) of the flat commutator (101), said bearing surface segments (112) being connected to the connecting segments (108) in a mechanically permanent, electrically conductive manner and the support body (102) and/or the connecting segments (108) being configured in one piece. The support body (102) is pre-fabricated and comprises openings (118), into which the connecting segments (108) are inserted. The commutator is characterised in that the connecting segments (108) are anchored to the bearing surface segments (112) on the support body (102) by means of the permanent mechanical connection, the openings (118) in the support body (102) comprise an extended section (124, 128) in the vicinity of the end of the connecting segment (108) that faces the bearing surface segments (112), the extended section (124, 128) of the openings (118) forms a receiving chamber for a connecting agent that joins the connecting segments (108) to the bearing surface segments (112) and once the connecting agent has cured, it anchors the connecting segment (108) to the support body (102). The invention also relates to a method for producing a flat commutator.
