AI Technical Summary

⚠Technical Problem

In existing food processing machines, the motor rotor rotates unevenly due to uneven mass distribution, resulting in vibration, noise, and bearing wear problems. Furthermore, dynamic balancing is complex and labor-intensive.

⚗Method used

By using a fan with a density lower than that of the balance block, dynamic balance correction is achieved through the one-piece molding of the first and second balance parts and the fan blades. Fine adjustment is made by utilizing the density difference of the fan, simplifying the correction operation and reducing material costs.

🎯Benefits of technology

It enables rapid and precise dynamic balancing of the rotor, reduces motor vibration and noise, simplifies the assembly process, and reduces material costs.
