Abstract
An electric work machine includes a brushless motor including a stator including a stator core, an electrical insulator located on the stator core, and at least one coil wound around the stator core with the electrical insulator in between, and a rotor rotatable with respect to the stator, and an output unit drivable by the brushless motor. The stator core has a through-hole and/or a recess to lock rotation of the stator with a screw.
