Abstract

The invention relates to an electric machine, comprising a stator (2), a rotor (3), a split cage (4), which separates a wet region (5) from a dry region (6), control electronics (9) and an interconnection element (7, 8), which produces an electrical contact between the stator (2) and the control electronics (9), wherein the rotor (3) is arranged in the wet region (5), wherein the interconnection element (7, 8) is surrounded at least partially by an insulating element (10), and wherein the insulating element (10) divides the dry region (6) into a first subregion (60), in which the stator (2) is arranged, and a second subregion (61), in which the control electronics (9) are arranged.
