ABSTRACT:
A sensor output for each axis of a five-axis control type magnetic bearing spindle is input to a multiplexer, time divisionally selected, converted to a digital signal by an A/D converter, and then applied to an MPU for control operation. Subsequently, a control signal is converted to an analog signal by a D/A converter for every axis, and A/D conversion, control operation and D/A conversion are sequentially processed.
