The invention provides a linear motor, an electromagnetic damping device and a vehicle. The linear motor comprises a rotor and a stator. The rotor is arranged on the outer side of the stator in a sleeving mode, and the rotor and the stator can move relatively in the axial direction. When the mover moves upwards from the initial position to the second limit position, the stroke is recorded as an upper stroke, and when the mover moves downwards from the initial position to the first limit position, the stroke is recorded as a lower stroke; in the down stroke, the effective combination length between the stator and the rotor is recorded as a first effective combination length, and in the up stroke, the effective combination length between the stator and the rotor is recorded as a second effective combination length; wherein the first effective combination length is smaller than the second effective combination length. Different effective combination lengths between the stator and the rotor in different strokes are set, so that different thrust expressions are realized in the up stroke and the down stroke of the linear motor, and different working condition requirements are met.

    本申请提供一种直线电机、电磁减振装置及车辆,直线电机包括动子和定子;所述动子套设在所述定子外侧且所述动子与所述定子可沿轴向相对运动;所述动子于初始位置向上运动至第二极限位置记为上行程,及所述动子于初始位置向下运动至第一极限位置记为下行程;在所述下行程中,所述定子与所述动子之间的有效结合长度记为第一有效结合长度,在所述上行程中,所述定子与所述动子之间的有效结合长度为第二有效结合长度;其中,所述第一有效结合长度小于第二有效结合长度。本申请通过设置不同行程中,定子与动子间不同的有效结合长度,保证直线电机上行程和下行程实现不同的推力表现,满足不同的工况需求。
