    • In the invention, a rotating elevator motor (6) provided with a traction sheave (18) is placed in the counterweight (26) of an elevator suspended with ropes (2). The sector-shaped stator (14) of the motor (6) has a diameter (2*Rs) larger than that (2*Rv) of the traction sheave (18) and the elevator ropes (2) are passed through the open part or parts (27) of the stator. This structure allows the use of traction sheaves (18) of different diameters with rotors (17) of the same diameter. Still, the length of the motor remains small and the motor/counterweight of the invention can be accommodated in the space normally reserved for a counterweight in an elevator shaft. The motor shaft (13) is placed in the counterweight (26) substantially midway between the guide rails (8) and the same number of ropes (2) are placed on both sides of the rotor (17).
