To achieve both securing of drive time by a motor and work efficiency.SOLUTION: A work machine includes: an engine; a motor generator; a battery capable of storing power generated by the motor generator; a stored-power measurement device capable of detecting a stored power amount of the battery and capable of detecting an increase and decrease in the stored power amount of the battery; an inverter that controls a rotation speed of the motor generator; and a control device that controls the motor generator to operate. The control device can change an output upper limit value that is set with respect to an output of the motor generator, and controls the inverter so as not to exceed the output upper limit value.SELECTED DRAWING: Figure 13 【課題】モータによる駆動時間の確保と作業効率とを両立する。【解決手段】作業機は、エンジンと、モータ・ジェネレータと、前記モータ・ジェネレータによって発電した電力を蓄電可能なバッテリと、前記バッテリの蓄電量を検出可能であるとともに、前記バッテリの蓄電量の増減を検出可能である蓄電測定装置と、前記モータ・ジェネレータの回転速度を制御するインバータと、前記モータ・ジェネレータを動作させる制御装置であって、前記モータ・ジェネレータの出力に対して設定される出力上限値を変更可能であり、前記出力上限値を超えないように前記インバータを制御する制御装置と、を備える。【選択図】図１３
