Abstract

An arrangement of an impeller (1) on an electrical motor, in particular on an external rotor motor (8), whereby the torque of the motor is transferred to the impeller (1) by means of a torsion-proof connection between the rotor (8) of the motor and the impeller (1) and/or its impeller hub (3), is characterised in that the connection of the impeller (1) to the motor (8) results from physical and/or chemical interactions between an adhesive medium (10) and the contact surfaces (5) of the impeller hub (3) and of the motor (8), which face each other, whereby the adhesive medium (10) fills, at least partially, an intermediate space (9) that is formed between the impeller (1) and the motor (8) by the given play.
