Embodiment Construction

[0034] refer to figure 1 Elevator system 20 may include a fixed support structure 22 (which may typically be an integral part of a multistory building) and at least one passageway or hoistway (i.e., the three hoistways 24, 26, 28 shown) having boundaries generally defined by structure 22. ). System 20 also includes at least one car 30 traveling within at least one of hoistways 24 , 26 , 28 . Car 30 may travel in a vertical direction, and may also travel in a dedicated upward direction in hoistway 26 and in a dedicated downward direction in hoistway 28 (as one non-limiting example). It is also contemplated and understood that the elevator system 20 may be self-propelled and may have a plurality of cars 30 traveling in any of the hoistways 24, 26, 28, with the plurality of cars traveling upward in the hoistway 26. and travel in the hoistway 28 in a downward direction.

[0035] The elevator system 20 may also include an upper transfer station 32 and a lower transfer station 34...

Abstract

An elevator system may include a stationary support structure defining a hoistway; a car disposed in the hoistway; a linear propulsion assembly (36) for applying a force to the car, the linear propulsion assembly (36) including a first rail (50) engaged to one of the support structure and the car, a plurality of magnets (48) mounted to the first rail (50), a second rail (44) co-extending with and spaced laterally from the first rail (50) and engaged to the other of the support structure and the car, and a plurality of electric coils (42) mounted to the second rail (44); and an active damper system (80) engaged to at least one of the first (50) and second (44) rails for damping vibration.

Description

Background technique [0001] The present disclosure relates to elevators, and more particularly, to multi-car, self-propelled elevator systems with linear propulsion systems. [0002] Self-propelled elevator systems, also known as ropeless elevator systems, are useful in certain applications (eg, high-rise buildings) where rope mass for rope-based systems is prohibited and where multiple elevator cars are desired to travel in a single passage. There are self-propelled elevator systems in which a first passage is designed for upward travel of the elevator car and a second passage is designed for downward travel of the elevator car. At least one transfer station is provided in the hoistway to move the car horizontally between the first and second aisles. [0003] Existing self-propelled elevators employ linear motors with an auxiliary section comprising permanent magnets embedded in a track-like structure. Due to the magnetic structure, the auxiliary part is usually under high ...
