Abstract
An electric work machine includes: a motor comprising a stator including coils, a rotor rotatable relative to the stator, and a rotor shaft fixed to the rotor; an output unit driven by the rotor shaft; a motor case including a main body having an insertion opening, and a lid disposed on one side in an axial direction relative to the main body and connected to the main body to close the insertion opening; and a resin portion that includes a first portion covering the coils and a second portion disposed on one side in the axial direction relative to the first portion. The first and second portions are integrated. Each of the first and second portions has a tubular shape. A second inner diameter indicating an inner diameter of the second portion is larger than a first inner diameter indicating an inner diameter of the first portion.
