Abstract
A brushless motor is at least partially located in a hermetically sealed space. An electric work machine includes a brushless motor, an output unit, a motor case, a lead wire, and a first seal. The brushless motor includes a stator, a rotor rotatable with respect to the stator, and a rotor shaft fixed to the rotor. The output unit is drivable by the rotor shaft. The motor case includes an internal space and a wiring passage. The internal space accommodates the stator and the rotor. The lead wire is located in the wiring passage connecting the internal space and an external space of the motor case. The first seal seals between the lead wire and the motor case.
