Title:
CONTROL DEVICE FOR HYBRID DRIVE-TYPE ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2005/108271
Kind Code:
A1
Abstract:
An electricity storage device (41) stores energy produced in regenerative operation of a cage (14) and supplies the stored energy to a drive system of the cage (14) in powered operation. A control device for hybrid drive-type elevator monitors energy capacity of the electricity storage device (41), and when the energy capacity is below a predetermined capacity, the control device changes the direction of travel of the cage (14) from a powered direction to a regeneration direction and stops the cage at the nearest floor. This prevents the cage (14) from stopping between floors due to the lack of energy to secure the safety of passengers.
