<p>In this invention, an elevator motor (6) provided with an external rotor (17) and a traction sheave (18) is so implemented that it simultaneously constitutes the counterweight (26) of a rope-suspended elevator (1). In this motor/counterweight structure, rotating induction motors can be used. A gear is not necessary because the construction of the invention and the placement of the motor allow the use of a motor with a large diameter and therefore a high torque. As the length of the motor still remains small, the motor/counterweight of the invention can be accommodated in the space normally reserved for a counterweight in an elevator shaft. <IMAGE></p> |
