PROBLEM TO BE SOLVED: To prevent or suppress deterioration of drive force of a power source when a voltage is not applied on an electromagnetic coil in a torgue estimation device and power control device of a gas compressor.SOLUTION: A torque estimation device 100 includes: a drive torque estimation part 110 which estimates and outputs drive torque of a gas compressor 200 provided with an electromagnetic clutch 210 for switching connection and disconnection by application stop and application of a voltage on the electromagnetic coil 211; and a response delay time estimation part 120 which estimates a response delay time from the application stop of the voltage on the electromagnetic coil 211 to actual disconnection of the electromagnetic clutch 210 in response to a resistance value of the electromagnetic coil 211 or a physical amount corresponding to the resistance value. The drive torque estimation part 110 continues estimation of the drive torque during the response delay time estimated by the response delay time estimation part 120.SELECTED DRAWING: Figure 1

    【課題】気体圧縮機のトルク推定装置及び動力制御装置において、電磁コイルへの電圧の印加がなくなったときに、動力源の駆動力が低下するのを防止又は抑制する。【解決手段】トルク推定装置100は、電磁コイル211への電圧の印加の停止と印加とによって断接を切り替える電磁クラッチ210を備えた気体圧縮機200の駆動トルクを推定して出力する駆動トルク推定部110と、電磁コイル211への電圧の印加の停止から電磁クラッチ210が実際に切断されるまでの応答遅れ時間を、電磁コイル211の抵抗値又は抵抗値に対応した物理量に応じて推定する応答遅れ時間推定部120と、を備え、駆動トルク推定部110は、応答遅れ時間推定部120により推定された応答遅れ時間の間は、駆動トルクの推定を継続する。【選択図】図1
