Abstract

A drive device for an impeller (17) which is rotatably mounted within a vessel (11) for stirring and mixing sterile fluids. The drive device is rotatably mounted at an inwardly-directed cylindrical recess (15) in a bottom wall (16) of the vessel, the recess (15) being intended to receive the drive device. The impeller (17) includes a peripheral section (21) which surrounds the cylindrical recess (15). A stator (24) is fixedly secured in the recess (15), which stator includes a magnetisable iron core (25) and induction coils connectable to a 3-phase alternating current source. Inductively magnetisable elements 23 are located in the peripheral section (21) of the impeller (17) for generating a torque when the stator (24) is supplied with a 3-phase alternating current so that the impeller rotates in a predetermined direction.
