Abstract
A shaft balancing device having first and second supports, which are rotatable about an axis, a motor drivingly coupled to the first support, an electromagnet, which has a plurality of coil units that are disposed circumferentially about the axis, and a control module. The control module is configured to separately control operation of each of the coil units to generate a predetermined composite magnetic field that is an aggregate of a plurality of magnetic fields produced by the plurality of coil units. The predetermined composite magnetic field is fixed relative to a datum that is rotatable about the axis with the first support. The control module is further configured to rotate the predetermined composite magnetic field about the axis at a rotational velocity of the first support.
