An electric work machine with a product structure that effectively reduces noise caused by a brushless motor without changing the motor specifications. A hammer drill includes a brushless motor including a stator including an insulator, a cylindrical stator core, and a coil wound around the stator core via the insulator, and a rotor rotatable relative to the stator, a cylindrical member fixed along an entire outer circumference of the stator core and made of material with a Young's modulus higher than a Young's modulus of the insulator, and a housing accommodating the brushless motor and the cylindrical member.
