Study of a Novel Approach of Active On-Line Balancing Device for High-Speed Spindle System
A spindle can be very sensitive to mass unbalance which may have destructive effect on many types of rotating machinery, especially in high-speed rotating equipments. In this paper, a new active on-line balancing device based on static magnetic field with simple structures was proposed. The consecutive configuration of related stator and rotor was designed; the discussion focused on how the structural parameters influence the electromagnetic force. In the end, the influence of the misalignment of both spindle and core on the electromagnetic force was analyzed numerically under a given condition.
