Abstract

A commutator for electrical machines has a segment carrier (1) made of an electrically conductive material and an outer casing (3) with longitudinal grooves (4) in which the segments (7) are inserted. An insulation (5) is placed between the longitudinal grooves (4) and the segments (7), which are fastened mechanically by displacement of material from the outer casing (3) of the segment carrier (1) into longitudinal grooves (11) in the fastening region (9) of the segments (7). Asbestos-free, heat-resistant commutators with high resistance to centrifugal forces are thereby obtained by simple means.
