    • PROBLEM TO BE SOLVED: To provide an electric working machine in which rotation of a motor is safely controllable, independent from output of a battery, and batteries with various output is detachably usable.
      SOLUTION: The electric working machine is configured as follows. When a main switch 12 is turned ON, the electric operating machine 1 is put in the standby mode, and when a trigger 13 is pulled in the standby mode, a power supply circuit 16 applies a voltage to a driving part 30. The power supply circuit 16 adjusts the voltage applied to the driving part 30 for a voltage corresponding to the pulling rate of the trigger 13. When the current running toward the driving part 30 exceeds the rated value of the driving part 30, the power supply circuit 16 automatically stops power supply to the driving part 30. On the other hand, when the output voltage of a battery 50 drops and the battery 50 is put in an overdischarge state, power supply to the driving part 30 is automatically stopped. When it is detected that the battery 50 undergoes an abnormal event, power supply to the driving part 30 is automatically stopped.

    • 要解决的问题:提供一种电动机的旋转是安全可控的电动工作机,独立于电池的输出,并且具有各种输出的电池可拆卸地使用。

      解决方案:电动工作机构如下。 当主开关12接通时,电动操作机1处于待机模式,并且当在待机模式下拉动触发器13时,电源电路16向驱动部分30施加电压。电源 电路16调整施加到驱动部件30的电压,使其对应于触发器13的拉出速度。当朝着驱动部件30行驶的电流超过驱动部件30的额定值时,电源电路16自动停止 电源供给到驱动部30.另一方面,当电池50的输出电压下降并且电池50处于过放电状态时,对驱动部30的供电自动停止。 当检测到电池50发生异常事件时,对驱动部件30的供电自动停止。 版权所有(C)2011,JPO&INPIT
