Abstract:
An electric work machine includes a motor in which a wire is wound around each tooth of a stator in an aligned manner. The electric work machine includes a motor including a rotor and a stator. The stator includes a stator core having a first end face and a second end face, and having teeth protruding inwardly, a first insulator covering the first end face, a second insulator covering the second end face, a rib located on at least one of the first insulator or the second insulator, and overlapping the teeth in an axial direction of the teeth, and coils including a wire wound around the teeth via the first insulator and the second insulator and the rib.
