Provided is an electric work machine in which it is possible to increase the magnetic force from a magnet provided in order to detect the rotation position of a rotor. An electric work machine having a brushless motor (24) that is provided with a rotor (28) and a stator (27), and a fan (36) attached to the rotor (28), wherein the electric work machine is provided with a permanent magnet (70) attached to the fan (36), a magnetic body (71) attached to the fan (36) and provided so as to be in contact with the permanent magnet (70), magnetism sensors (S1-S3) for detecting the magnetic force formed by the permanent magnet (70), and a rotation position detection circuit for detecting the rotation position of the rotor (28) on the basis of the detected magnetic force. |
