Abstract

PURPOSE: To minimize the capacity of emergency power source, by controlling the elevator operation by use of the emergency power source, depending on the load of passengers in the elevator cage at the instant after passing of a certain time period from the time when elevator is stopped due to interruption of power supply.
CONSTITUTION: If power supply from service power source NV is interrupted during operation of elevator, elevator is stopped immediately and at the same time connection of elevator driving motor M to service power source NV is switched to emergency power source EV. Here, if load in elevator cage F at the time instant after passing of a certain time period from the time when power supply from service power source NV is interrupted is less than 50% of the rated load, elevator is driven upward. On the other hand, if it is more than 50% of the rated load, elevator is driven downward.
