Component for a Rotor of an Electric Machine Having a Slot Insulation Element and Heat Sink

Abstract

The invention relates to a component (30) for lining a slot (7) that is formed between two poles of a rotor core (2) of a rotor (1) and that extends axially between two end faces (9) of the rotor core (2), having a slot insulation element (15) for electrically insulating winding sections, arranged in the slot (7), of windings (45) of the rotor (1) from the rotor core (2), which slot insulation element has two side regions (21) for resting on slot edges (16) of the slot (7) and a base region (22) to be arranged so as to overlap with a slot base (17) of the slot (7), wherein a bottom (26), facing the slot base (17), of the base region (22) of the slot insulation element (15) has an axially extending notch (27) and the component (30) has a heat sink (29) having at least one cooling fluid-carrying cooling channel (33) for cooling the winding sections arranged in the slot insulation element (15), which heat sink is arranged in the notch (27) of the slot insulation element (15) so as to be arranged on the slot base (17) and is mechanically connected to the slot insulation element (15).
