Abstract:
A hybrid work machine includes a turning electric motor configured to turn an upper-part turning body, a hydraulic actuator, and a controller configured to control turning in a state of an independent turning operation by the turning electric motor and in a state of a combined turning operation by the turning electric motor and the hydraulic actuator. The controller is configured to limit the output of the turning electric motor in the state of the independent turning operation after a transition from the state of the combined turning operation to the state of the independent turning operation to an output smaller than the output of the turning electric motor in the state of the independent turning operation other than the state of the independent turning operation after said transition.
