Provided is an electromagnetic suspension that suppresses interference with other components or devices, can be mounted in a narrow space, has small pulsation of thrust force, has large thrust force, and has high vibration damping properties with respect to a high-frequency vibration source. An electromagnetic suspension according to the present invention is an electromagnetic suspension using a linear motor having an armature composed of a winding and a magnetic body; and a permanent magnet part disposed on the outer peripheral side of the armature and comprising a permanent magnet and a cylindrical magnetic body, in which the armature and the permanent magnet part are linearly driven relative to each other. A recessed portion recessed relative to an outer peripheral portion and a protruding portion protruding relative to the outer peripheral portion are disposed on the same circumference of the outer peripheral portion of a cylindrical magnetic body.
本发明提供一种抑制与其他零件或设备的干涉、能搭载于狭小空间内、推力的脉动小、推力大、对于高频振动源而言减振性也高的电磁悬架。本发明的电磁悬架是一种使用线性马达的电磁悬架,所述线性马达具有由绕组和磁性体构成的电枢;以及配置在电枢的外周侧、由永磁铁和圆筒状的磁性体构成的永磁铁部,电枢和永磁铁部相对地作直线驱动,该电磁悬架的特征在于,在圆筒状的磁性体的外周部的同一圆周上配置相较于该外周部而言凹陷的凹部和相较于该外周部而言突出的凸部。
