Abstract

The invention relates to an electronically commutated electric machine (1), comprising a stator housing (3) which receives a stator (4) in a stator chamber (13) and which delimits a rotor chamber (14) receiving a rotor. According to the invention, the stator housing (3) comprises a main housing (31) and a cover (9), wherein an elastic sealing element (8) is arranged between the main housing (31) and cover (9) and extends into the inside of the stator housing (3) with at least one radial region (30) and forms a tolerance compensating element (19) acting on the stator (4).
