Abstract
Provision of a digital controller in which the controller controls the bearing coil current by means of a switching bridge that periodically reverses the applied voltage to the coil. The controller selects an applied voltage from a plurality of discrete voltage sources. When a rapid change in the load current is required, a relatively large magnitude of applied voltage is used. When a relatively constant magnitude of average load current is required, a relatively smaller value of voltage is applied.
