Abstract

See full text

A lift drive system for an energy storage and delivery system includes an electric motor that rotates a driven shaft, a brake assembly for selectively braking the rotation of the driven shaft, and optionally includes a clutch selectively operable to decouple the electric motor from the driven shaft. A steel ribbon is disposed at least partially about and in contact with the driven shaft, where rotation of the driven shaft by the electric motor causes linear movement of the steel ribbon. The steel ribbon can connect at one end to an elevator cage assembly and at an opposite end to a counterweight.
