ABSTRACT:
In a gas circulation fan, a main shaft is supported in a non-contact manner, by magnetic bearings. Between each of the magnetic bearings and a controller, a relay is provided. Each relay includes a position detection sensor circuit, an offset adjuster, a feedback gain adjuster and a filter circuit. Thus, compatibility between a mechanical body unit and the controller is attained.
