<P>PROBLEM TO BE SOLVED: To provide a speed control device for an evacuation elevator improved in evacuation efficiency in evacuation when operation patterns of a hoist motor with a margin in ability thereof are concentrated. <P>SOLUTION: This evacuation elevator to be operated between a fire floor and an evacuation floor when a fire detecting signal is generated is provided with a balance device 8, a fire alarm, a position detecting unit 9, a speed command generating unit 10 for computing a speed command of the hoist motor 1 of an elevator car corresponding to a distance to a target floor on the basis of a load detecting signal, the fire detecting signal and a position detecting signal, and a current control unit 12 for controlling current of the hoist motor 1 on the basis of the speed command. The speed command generating unit 10 outputs a speed command for increasing at least one of speed and acceleration in comparison with normal operation when a fire is detected and a car-inside load is within a light load range on a no-load side more than a normal load range and in rising operation or when a car-inside load is in a heavy load range on a rated load side more than the non-load range and in lowering operation. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
