Abstract: In a drive arrangement for a heavy duty mill an electric motor with a high number of magnetic poles and a stator that is segmented into at least four stator segments is used. By providing one, more or all of the stator segments with a three phase winding system, a highly modular mill drive with a high power density and therefore reduced space requirements is provided.

Abstract: The invention relates to a heavy-duty drive arrangement (1) for a mill having a grinding bowl (2) that can rotate about the vertical axis (A), said drive arrangement comprising a housing (6), an electric motor (5) and a gearbox arrangement (4) disposed in the housing (6) and supported on the housing (6). The grinding bowl (2) can be driven by the electric motor (5) by means of the gearbox arrangement (4). The electric motor (5) is disposed below the gearbox arrangement (4). The electric motor (4) is integrated in the housing (6). The electric motor (5) is advantageously supported on the housing (6), particularly on a base element (6c) of the housing (6). The rotor (7) can be connected directly, or by means of a clutch integrated in the rotor, to a wheel (11) of the gearbox arrangement (4). The mill is, for example, a bowl-and-roller mill.
