<p>PROBLEM TO BE SOLVED: To provide an elevator capable of operating for a short time even when power supply is interrupted. SOLUTION: An elevator box driving part 1 is provided with an elevator motor 11, a motor control circuit 12 and an electric double layer condenser 13. While all of a wind power generation part 2, a solar battery part 3, an ordinary power source part 4 and a power source line 5 are normal, the electric double layer condenser 13 connected with the motor control circuit 12 in parallel is charged by direct current supplied from the wind power generation part 2, the solar battery part 3 and the ordinary power source part 4. For instance, when an electric power station stops power supply for a lightning protection, a calm state and a dark state are made and direct current is not supplied from all the wind power generation part 2, the solar battery part 3 and the ordinary power source part 4 to the elevator box driving part 1, the motor control circuit 12 is operated by power stored in the electric double layer condenser 13.</p> |
