Abstract: A belt and sheave assembly for an elevator system includes a sheave having a plurality of tracking grooves laterally spaced across a sheave width, and a debris channel located in a tracking groove of the plurality of tracking grooves defining a radially inwardmost extent of the tracking groove. The assembly further includes a belt having a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, a jacket at least partially enclosing the tension members, the jacket defining a side of the belt configured to interface with the sheave, and a plurality of tracking features extending from the side of the belt. The tracking features are laterally spaced across the belt width. Each tracking feature is configured to be received in a tracking groove, and each tension member is laterally offset from each of the tracking features.

Abstract: According to an aspect, an elevator system includes a propulsion system having a plurality of motor segments forming a primary portion and a plurality of drives to impart force on a secondary portion coupled to an elevator car. The elevator system also includes a controller operable to identify a local neighborhood of the drives and determine a health status of each of the drives within the local neighborhood. The controller is further operable to adjust a thrust command per active drive of the local neighborhood based on at least one of the health status and a position of each active drive of the local neighborhood with respect to the secondary portion.

Abstract: An elevator system includes a lane and at least one rail extending along the lane. An elevator car is arranged in the lane and is operatively coupled to the at least one rail. The elevator car has a predetermined alignment relative to the at least one rail. A propulsion system is operatively connected between the elevator car and the at least one rail. A thrust and moment control system is operatively connected to the propulsion system. The thrust and moment control system selectively controls the propulsion system to substantially maintain the predetermined alignment of the elevator car relative to the at least one rail.

Abstract: An illustrative example embodiment of an elevator system includes a plurality of components respectively configured for at least one function during operation of the elevator system. A plurality of sensors are each associated with at least one of the components. Each sensor senses at least one characteristic of an actual performance of an associated one of the components. A processor is configured to receive respective indications from the sensors regarding the actual performance of the associated components, determine a difference between the actual performance and a desired performance of any of the components based on the respective indications, and determine an adjustment to the operation of the elevator system based upon the determined difference.
