An electric working machine according to one aspect of the present disclosure includes an output shaft, a motor, a transmitting device, a drive device, a controller, and a current path. The transmitting device has transmittable allowable torque and transmits rotation of the motor to the output shaft. The drive device energizes the motor with electric supply from a battery in accordance with a command from outside the electric working machine. The current path is configured to be able to energize the motor with a current value larger than an allowable current value required to limit torque generated in the transmitting device due to rotation of the motor to the allowable torque or smaller.

Electric working machine

An electric power tool of an embodiment of the present invention uses a motor provided with a yoke as a drive source, and is configured such that an end portion of an electric component mounted on a drive circuit of the motor is electrically connected to the yoke of the motor through a conductive elastic body.

Electric power tool having a conductive elastic body connected to a yoke

An electric power tool has an electric motor disposed in a main body and a power supply circuit electrically connected to the electric motor by wires to supply electric power to the electric motor. A switch is disposed in the power supply circuit so as to electrically open and close the power supply circuit. A movable member is supported by the main body, a detector is disposed in the main body to detect a movement of the movable member and the switch is configured to electrically open the power supply circuit when the detector detects the movement of the movable member. The wires connected to the electric motor are not connected to the detector so that the length of the wires is shortened.
