Abstract
An electric work machine is driven appropriately. An electric work machine includes a motor including a stator, a rotor rotatable relative to the stator, and a rotor shaft fixed to the rotor, an output unit drivable by the rotor shaft, a plurality of heat-radiating fins, a motor case having an outer surface receiving the plurality of heat-radiating fins and accommodating the stator and the rotor, a cooling fan located outside the motor case and rotatable by the rotor shaft, and a duct including a guide to guide air through the cooling fan to a fin passage between adjacent heat-radiating fins of the plurality of heat-radiating fins.
