To monitor a state of an electric switch machine by highly accurately estimating output torque and a conversion load of a clutch rotation shaft even in a state where the clutch is slipping by using a method not requiring noise countermeasures and the like without causing any problems in durability.SOLUTION: An electric switch machine state monitoring device includes a clutch output shaft torque estimation processing unit 41, which acquires a current value and a voltage value of a motor of an electric switch machine and rotation speed of an output shaft of a clutch of the electric switch machine, calculates an estimated maximum torque of the motor and a rotation speed ratio of the motor and the clutch, and calculates an estimated value of the torque of the output shaft of the clutch based on a correlation between the rotation speed ratio of the motor and the clutch and a torque ratio of the motor and the clutch.SELECTED DRAWING: Figure 5

    【課題】耐久性に問題が発生せず、ノイズ対策等を必要としない手法を用いて、クラッチが滑っている状態においても、クラッチ回転軸の出力トルクや転換負荷を高い精度で推定して、電気転てつ機の状態を監視する。【解決手段】電気転てつ機のモータの電流値および電圧値、並びに、電気転てつ機のクラッチの出力軸の回転速度を取得して、モータの推定最大トルク、および、モータとクラッチの回転速度比を算出し、モータとクラッチの回転速度比とモータと、クラッチのトルク比との相関関係に基づいて、クラッチの出力軸のトルクの推定値を算出するクラッチ出力軸トルク推定処理部41を有する。【選択図】図5
