An electric work machine () includes a motor () having a rotor () disposed within a stator core () and coils () disposed on the stator core; a power-transmission mechanism () driven by the rotor; and an output shaft (), on which a tool accessory is mountable and which is operably driven by the power-transmission mechanism. The stator core includes an outer-side member () having projection parts () protruding radially inward from a circular-ring part () in a spaced apart manner in a circumferential direction of the stator core and respectively supporting the coils; and an inner-side member () disposed radially inward of the outer-side member and coupled to inner-end portions of the projection parts. A plurality of first insulators () and a plurality of second insulators () may be respectively disposed around the projection parts and interconnected in an alternating manner in the circumferential direction.
