In a vacuum cleaner blower (1) consisting of an electric drive motor (2) and a support cage (10) for receiving the structural modules of the drive motor such as stator pack (6), rotor (7) and brush holders (8) including carbon brushes (9) as well as an at least single stage blower unit driven by the motor including a deflector (11), impeller (12) and suction hood (4), the deflector being formed as a support cage lid including a bearing seat for the rotor (7) and the support cage (10) being formed for a mounting direction (C) of its structural modules in the axial direction of the blower and for direct contacting and the brush holder (8) of the carbon brushes being provided adjacent to the upper side (B) of the support cage which also faces the deflector (11). Because of this specialty, all structural modules essential for the electric motor aggregate such as stator pack, rotor, rotor bearing as well as brush holder including carbon brushes may for the completion of the suction blower be successively and fully automatically be inserted and secured in their proper disposition into the support cage (10), without additional fastening elements, in a preferred assembly and mounting direction (C). During mounting direct contacting of the electrical connectors of the stator (6) and carbon brushes (9) or brush holders (8) takes place as well without changing the assembly direction.
