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.
