Abstract: An elevator system has an elevator car suspended on at least one synchronous belt driven by a drive driving a drive pulley in a non-slip manner, a distance measurement device measuring a travel distance of the belt at the drive pulley for determining a car position, a controller actuating the drive based on-stored stop location position values and a determined car position to stop the car at two or more stop locations, at least one position sensor disposed from the drive pulley and signaling the controller when the car passes a reference position, and a compensation device making a correction of the stored stop location position values with a correction factor based on the difference between the car position determined by the distance measurement device and the reference position as the car passes the reference position. Methods for operating the elevator system and initializing the controller are provided.

Abstract: A traction drive for an elevator comprises a sheave for actuating a transmission device of the elevator and a synchronous motor, the synchronous motor comprising a stator with at least one winding for generating a magnetic field rotating around a motor axis and a rotor comprising at least one permanent magnet, the rotor being coupled to the sheave for transmitting a torque. The permanent magnet is longer in the motor axis direction than the stator core and/or the rotor is composed from a plurality of separate permanent magnets and separate magnetic sectors provided alternating in a circumferential direction perpendicular to the motor axis to concentrate the magnetic flux in axial and/or radial direction.

Abstract: An elevator comprises a cabin with a cabin floor and at least a compensation chain or rope being connected by a fixation point to the cabin floor. A displacement element is provided between the cabin floor and the chains or ropes to displace the fixation point in dependence on the weight force and torque applied by the compensation chain or rope to the cabin floor. The displacement cancels out the torque that would otherwise be present when a fixed off-center fixation point is employed.
