The housing of an electrical machine should, despite efficient cooling, be provided with a more compact design. To this end, the invention provides that the cooling ducts (2) of a housing (1), which is preferably provided in the form of an aluminum extruded profile, are left open toward the inside. The inner walls of the cooling ducts (2) are then formed by an inserted stator pack (4). This enables the corner areas of the housing to be kept free for assembly and the reduction of material for manufacturing the housing (1). In addition, due to the open cooling air ducts (2), thin wall thicknesses in the profile and thus small motor dimensions while simultaneously having a large cooling duct cross-section can be realized.
