Summary:PURPOSE: A winch used for an elevator is provided to conveniently install by reducing the size of a rotor toward an axial direction or a rotational radius direction. CONSTITUTION: A winch comprises a shaft(12); a stator(13) arranged along the circumferential direction of the shaft; an inner void(18a) formed to be parallel with an outer void(18b); a rotor(15) rotating on the shaft; a driving motor(11) having the rotor; and a winding sheave(17) engaged to the shaft to integrally rotate with the rotor. The winch forms the stator and the rotor while separating from each other to concentrically form the inner and outer voids around the shaft. Thereby, the length of the shaft in an axial direction is reduced than an existent internal rotating typed driving motor when the same torque is needed.
