ELECTRIC WORKING MACHINE

摘要

An electric working machine according to one aspect of the present disclosure includes a motor, a current detector, a voltage detector, and a load state determination unit. The current detector is configured to detect a current flowing through the motor during drive of the motor. The voltage detector is configured to detect an input voltage supplied to the motor during drive of the motor. The load state determination unit is configured to determine whether the motor is in a no-load operation state based on the detected current, the detected input voltage and an output voltage from an electric power source.

主权项

1. An electric working machine comprising:
a housing; a mount configured to mount one of a tool bit and an edged tool for carrying out work to a workpiece; a motor that is built in the housing and configured to be driven by electric power supplied from an electric power source to drive the mount; an operation switch for driving the motor; a current detector configured to detect a current flowing through the motor during drive of the motor in association with an operation of the operation switch; a voltage detector configured to detect an input voltage supplied to the motor during drive of the motor; and a load state determination unit configured to determine whether the motor is in a no-load operation state in which no work is carried out to the workpiece during drive of the motor, based on the current detected by the current detector, the input voltage detected by the voltage detector, and an output voltage from the electric power source.
