PURPOSE: A control magnetic bearing device is provided to stably rotate a rotor. CONSTITUTION: A DSP(7)(digital signal processor) sends a motor controlling signal to an inverter(9). The inverter drives a motor(5) to generate a certain rotating torque, rotating a certain velocity. An A/D converter(6) converts the output of a displacement sensor(3) to a digital signal. The digital signal is input to the DSP. The DSP operates the digital signal per certain sampling time based on the certain control property and outputs a magnetic bearing control signal for a magnetic bearing driving circuit(8). The driving circuit drives a magnetic bearing (4) based on the magnetic bearing control signal. Therefore, the position of a rotor(R) is controlled.
