Abstract
An elevator system comprises an elevator car, a direct current motor, an alternating current power source, a voltage transformation rectifier circuit and a variable-speed gear transmission device and further comprises an energy storage device and a voltage transformation rectification charging circuit. When an elevator descends, the direct current motor is driven by the variable-speed gear transmission device to reversely rotate through the gravity of the elevator car, the direct current motor can be regarded as a power generator to output the alternating current power source during reverse rotation, the alternating current power source is converted into a direct current power source usable for the energy storage device through the voltage transformation rectification charging circuit, and the energy storage device is charged. When the elevator ascends, the electric energy stored in the energy storage device and the alternating current power source are utilized for jointly driving the direct current motor through the voltage transformation rectifier circuit, and the direct current motor converts the electric energy into kinetic energy to drive the variable-speed gear transmission device to drive the elevator car to ascend. According to the elevator system, electric energy waste in the elevator running process can be reduced.
