Development of Hybrid Magnetic Spindle-Synchronous Control with Rotation

This report concerned with the hybrid magnetic spindle, which consists of air bearings and magnetic bearings. This is developed Lo use as the main spindle of machining center. In this report, to eliminate the influence the of unbalance, a synchronous control with rotation is used in addition to PID control. This control system consists of the DSP and anaing circuits. As a result, it is clarified that with the synchronous control, the whirling amplitude spindle can be smaller and the higher rotating speed is attained.
