This invention pertains to blending in cylindrical vessels, e.g. in bioreactors. It can be used in biotechnology, chemical technology, and other branches of the industry.The object of this invention is to ensure the linear speed of the blender within the range of 0.03-3.0 m/s, and the conservation of the energy supplied to the stator spools. Thus, the quality of blending is enhanced, equipment maintenance is simplified, and it also becomes possible to improve the technological characteristics of the equipment.The essence of this invention is as follows: a Hall generator and a mode setting panel, both connected to the control pulse shaper, as well as the power amplifier connected to the stator spools, in which the angle between the magnets arranged in the circumference of the magnetic stator is no less than 10 degrees (fig.1), are additionally included into the circuit inside the drive control unit.<IMAGE>
