Abstract
An electric work machine includes a brushless motor shortened in the direction of a motor shaft and allowing the rotational balance of a rotor to be easily adjustable. The electric work machine includes a brushless motor including a stator and a rotor, and at least one motor bearing supporting the rotor in a rotatable manner. The rotor includes a magnet being cylindrical and a magnet holder being hollow cylindrical or solid cylindrical. The magnet holder has a recess recessed in an axial direction, holds the magnet with the magnet being exposed in a radial direction, and has an axial length longer than the magnet. The magnet holder is partially exposed. The at least one motor bearing is at least partially received in the recess.
