ABSTRACT:
A magnetic bearing apparatus supports a rotating object using magnetic levitation by a magnetic force of electromagnets. The magnetic bearing apparatus includes a PWM driver configured to supply exciting currents to the electromagnets, a driver power source configured to drive the PWM driver, and a displacement error signal removing section configured to extract a displacement error signal of the displacement information from a current flowing through the driver power source and to remove the displacement error signal from the displacement information.
