摘要： 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.
