Abstract: The invention concerns a method of mounting a compressor block on a front side of a stator of an electric motor that comprises a stator bore and a stator axis, a support face arrangement of the compressor block being mounted on a contact area of the stator front side and the compressor block being connected to the stator. It is endeavoured to manufacture a compressor arrangement with a high efficiency. For this purpose, before mounting the compressor block (2) on the contact area (21, 22), the stator (4) is acted upon with a clamping force corresponding to a mounting force, a spatial deviation of the contact area (21, 22) from a plane, to which the stator axis (17) is perpendicular, is determined, the support face arrangement is machined so that the deviation is compensated, and the compressor block (2) is connected to the stator (4).
