[0033] The electromagnetic drive device of the present invention is a permanent magnet synchronous motor, which has the characteristics of high control accuracy, high torque density, good torque stability and low noise.

The stirring shear force is generated, and the stirring hole 15 is used for rapid stirring. At the same time, the small electromagnetic drive device 10 drives the push-type stirring blade 11 to rotate, so that the push-type stirring blade 11 pushes the material and cells to move toward the stirring blade 8, thereby facilitating the stirring of the stirring blade 8, and the stirring is more uniform and efficient. When in use, the vibration generated by the horizontal stirring drum 2 is supported and buffered by the supporting rib plate 17 of the supporting buffer mechanism 13. At the same time, when the vibration force is too large, the pushing block 18 is driven to push the sliding block 19 to slide and compress the buffer spring 20 to assist in buffering, thereby better buffering and protecting the horizontal stirring drum 2.
