소용량의 전동 모터(MG)를 이용하여 연속작동시간이 짧은 작업기계의 액추에이터를 작동시킬 때에는 전동 모터를 정격용량을 넘은 범위에서 회전시키고, 연속작동시간이 긴 주행중에는 전동 모터를 정격용량 이하로 회전시킨다. 컨트롤러(C)는 이 건설기계가 주행 모드에 있는지 주행 정지작업모드에 있는지를 모드 센서(5a, 12a)로부터의 신호로 판정한다. 그리고 주행 정지작업모드에 있다고 판정했을 때에는 컨트롤러(C)는 전동 모터(MG)가 정격용량을 넘은 범위에서 회전하는 고출력 설정으로 한다. 또 통상, 주행 모드에 있을 때에는 컨트롤러(C)는 전동 모터가 정격용량 이하에서 회전하도록 저출력 설정으로 한다.

    When an actuator in an operational mechanical system having a short continuous operation time is operated using a small-capacity electric motor (MG), an electric motor is rotated in the range exceeding a rated capacity, and during traveling with a long continuous operation time, the electric motor is rotated at the rated capacity or less. A controller (C) determines, from signals from mode sensors (5a, 12a), whether the construction machine is in traveling mode or in traveling halt operation mode. When determining that the construction machine is in the traveling halt operation mode, the controller (C) sets the construction machine to a high output setting in which the electric motor (MG) rotates in the rage exceeding the rated capacity. In the normal traveling mode, the controller (C) sets the construction machine to a low output setting so that the electric motor rotates at the rated capacity or less.
