An existing laterally control flux-path mechanism has a seesaw mechanism to move a flux-path control plate. Therefore, the size of the apparatus is rather large. To reduce a size of suspension system, a novel flux-path control mechanism is proposed which adjusts the flux reaching the floator by rotational motion mechanism. The principle of the adjustment is similar to that of reluctance motor. A geared-shaped yoke is attached to the side of the permanent magnet. A geared-shaped control plate facing the yoke is rotated to change the relative angle between the gear-shaped control plate (outer) and the gear-shaped yoke (inner). To verify the efficacy of this mechanism, magnetic field analyses are carried out. Then a magnetic suspension apparatus is developed based on the analyses.
