The present application relates to a drive unit for an agitator, which may be attached to the bottom, wall or cover of a mixing vessel. The agitator is especially applicable to purposes where a relatively large and slowly rotating agitator is required. Thus, for example, agitators used in dilution vessels and the like of wood processing industry come into question. A characterizing feature the drive unit for the agitator in accordance with the present invention is that the drive unit of the agitator comprises a disc (48) attached to an end of an agitator shaft (42) opposite to an agitator means (20), and a casing (50) surrounding said disc in such a way that the disc (48) is provided with permanent magnets operating together with coils (56) arranged to at least one wall (52, 54) of the casing (50) surrounding the disc (48) or in connection therewith forming a permanent magnet motor.
