PROBLEM TO BE SOLVED: To provide a rolling stock vibration control device which is capable of protecting a motor from an overload and also avoiding interruption of vibration control.SOLUTION: A rolling stock vibration control device 1 includes: an actuator A disposed in rolling stock which includes a cylinder body Cy that expands and contracts upon supply of a working fluid, a pump 12 that supplies the working fluid to the cylinder body Cy, and a motor 15 that drives the pump 12; and a control section C to control the motor 15. The control section C is designed to stop the motor 15 when a current value I to be supplied to the motor 15 becomes equal to or more than a current threshold value Iα to output a limit torque to be set to a value exceeding a rating torque of the motor 15.SELECTED DRAWING: Figure 2

    【課題】モータを過負荷から保護できるとともに、制振制御の中断を回避できる鉄道車両用制振装置の提供である。【解決手段】鉄道車両用制振装置1は、作動流体の供給により伸縮するシリンダ本体Cyと、シリンダ本体Cyへ作動流体を供給するポンプ12と、ポンプ12を駆動するモータ15とを有して鉄道車両に設置されるアクチュエータAと、モータ15を制御する制御部Cとを備え、制御部Cは、モータ15へ与えるべき電流値Iがモータ15の定格トルクを超える値に設定される制限トルクを出力させる電流閾値Iα以上になるとモータ15を停止する。【選択図】図2
