Abstract:
1. A hybrid working machine, comprising: a hydraulic pump for driving a hydraulic actuator; a generator motor for performing a generator action and a motor action; an engine serving as a common power source for said hydraulic pump and said generator motor; an electric storage device electrically charged by the generator action of said generator motor, the electric storage device being configured such that said generator motor is driven by electric power of the electric storage device so as to perform the motor action; accelerator operating means for changing a fuel injection amount so as to control rotation speed of said engine; and generator output controlling means for controlling generator output of said generator motor, wherein said generator output controlling means for limiting the generator output in a process of accelerating the rotation speed of said engine to set speed determined on the basis of the operation of said accelerator operating means.
