To provide an electromagnetic suspension that suppresses variation in a gap length between a stationary element and a movable element which occurs due to stress in other directions than a propulsive direction of an electromagnetic suspension, and has a high damping robust property.SOLUTION: An electromagnetic suspension 100 includes: a pair of shafts 21 connecting between frames and facing each other; a linear motor 10 including a stationary element 11 including an armature core and an armature coil and a movable element 12 fixed between the frames, having a magnet or magnetic material with a first surface and a second surface opposed to the stationary element and moving relatively to the stationary element 11; and an elastic body 20 fitted to the shafts 21 while being compressed between one of the frames and a bearing 22 that is an arm of the stationary element 11.SELECTED DRAWING: Figure 1 【課題】電磁サスペンションの推進方向以外の応力によって発生する固定子と可動子のギャップ長の変化を抑制し、制振ロバスト性の高い電磁サスペンションを提供する。【解決手段】電磁サスペンション１００は、フレーム間を繋ぐ対向する一対のシャフト２１と、電機子鉄心と電機子巻線とを有する固定子１１と、フレーム間に固定され、固定子に対向する第１の面と第２の面とを有する磁石または磁性体を有し、固定子１１に対し相対的に移動する可動子１２と、を有するリニアモータ１０と、シャフト２１に装着され、フレームの一方と固定子１１の腕である軸受け２２とで縮接されている弾性体２０と、を備える。【選択図】図１
