1. An electric work machine, comprising:
a motor including
a stator including a stator core and an insulator at least partially fixed to a front portion of the stator core, and
a rotor at least partially located radially inward from the stator, the rotor being rotatable about a rotation axis;
a spindle located frontward from the stator core in a front-rear direction parallel to the rotation axis, the spindle being rotatable under a rotational force generated by the rotor;
a spindle bearing supporting a rear portion of the spindle in a rotatable manner, the spindle bearing being located radially inward from the stator; and
a bearing box holding the spindle bearing, wherein
the insulator is connected to the bearing box, and
the spindle bearing and the stator at least partially overlap each other in the radial direction and at least partially located at a same position in the front-rear direction.
