Abstract:
To provide an electric work machine, which is configured so that a motor can be suppressed from being deteriorated due to overcurrent without detecting currents flowing into the motor.SOLUTION: The electric work machine comprises a motor, a detection part that detects rotation speed of the motor, and a control part that drives the motor by predetermined driving power. The control part is configured to restrict the driving power for the motor so that the driving power for the motor becomes lower as the rotation speed is lower, according to the rotation speed detected by the detection part.SELECTED DRAWING: Figure 3
