Abstract

An exemplary elevator system includes an elevator car situated for movement within a hoistway. An elevator drive provides control over a position of the elevator car in the hoistway. A backup power source provides power when the primary power source is unavailable. An emergency controller uses power from the backup power source for controlling the position or movement of the elevator car within the hoistway when the primary power source is unavailable. The elevator drive, the emergency controller and the backup power source are all supported together in a single location within the hoistway.

Claims

1. A machine roomless elevator system, comprising:

an elevator car situated for movement within a hoistway;

an elevator drive for controlling a position or movement of the elevator car in the hoistway, the elevator drive utilizing power from a primary power source;

a backup power source; and

an emergency controller that uses power from the backup power source for controlling the position or movement of the elevator car within the hoistway when the primary power source is unavailable, the backup power source, the elevator drive and the emergency controller all being supported together in a single location in the hoistway.

2. The system of claim 1, wherein the single location is near a top of the hoistway.

3. The system of claim 1, wherein the single location is on the elevator car.
