Abstract: An electric work machine has less size increase. An electric work machine includes a power supply device, a first electric component, a second electric component, a first electric wire connecting the power supply device and the first electric component, a second electric wire connecting the power supply device and the second electric component, a power supply housing accommodating the power supply device, a first housing accommodating the first electric component, a second housing accommodating the second electric component, and a sheath accommodating the first electric wire and the second electric wire. The sheath has a first end located inside the power supply housing, and a second end located inside the first housing. The second electric wire extending from the sheath is placed in the second housing.

Abstract: A power tool, for example, a portable circular saw, includes a fan, a motor configured to rotate the fan, an output part or shaft driven by the motor, a motor housing that houses the motor, a grip housing connected to the motor housing, a trigger associated with the grip housing, and a brake member configured to brake a rotation of the motor, the brake member being mounted inside the grip housing. The brake member may be a resistive element of a rheostatic braking system. The housing and fan are configured such that cooling air is directed to cool the brake member.
