摘要： PROBLEM TO BE SOLVED: To miniaturize a magnetic bearing device by dispensing with a distance sensor.
SOLUTION: Ring-shaped two electromagnets 10a, 10b and permanent magnets 16a, 16b are mounted through a controlled member 30, and a PWM power source 15 applies the electric power to a bridge circuit composed of the electromagnets and two load elements 17a, 17b. A signal processing circuit 18 receives signals from output terminals OUT1 and OUT2 of the bridge circuit, and operates the difference in amplitudes of the receives signals. When the controlled member 30 is displaced in the a or b direction, the difference in amplitudes is not zero, so that the signal processing circuit 18 operates the adjustment voltage to equalize inductances of two electromagnets 10a, 10b. The adjustment voltage is compensated by a compensating circuit 14 to stabilize the close circuit characteristic of a control system, and supplied to the PWM power source 15, whereby the PWM power source 15 adjusts the outputted average voltage by modulating pulse widths.

摘要： PROBLEM TO BE SOLVED: To provide a sensor-less magnetic bearing control device having a simple system structure without requiring a special digital arithmetic processing.
SOLUTION: A bias voltage source 12 for supplying a bias current required to maintain the linear characteristic of electromagnets, and a control current source 7 for supplying the exciting current required to control a rotor to be floated for support at a desirable position, while overlapping with the bias current from the bias voltage source, are connected to the electromagnets 10 and 11 forming a magnetic bearing. The exciting current output from the control current source is supplied to the pair of electromagnets, which are arranged opposite to each other, at an opposite duty ratio by controlling the magnetic bearing control voltage source to modulate an amplitude of the pulse. The duty ratio is controlled so that impedance of each of the pair of electromagnets, which changes in response to position of the rotor 13, becomes equal to each other.
