Abstract: The application relates to a stator frame of an electrical machine having a first end and a second opposite end. A flange is protruding from the first end and surrounding the first end. The stator frame includes cooling fluid channels and cooling fins on the outer surface of the stator frame extending from the first end to the second end. The stator frame is formed as a single piece. The ends of the outer walls of the cooling fluid channels in the first end are connected to the flange and the cooling fins extend to the junction of the flange and the first end.
