Summary: | The utility model relates to an energy-saving automatic escalator which comprises steps, a driving device for driving the steps, and a control device for controlling the driving device to work; the control device comprises an on/off device for controlling the on and the off of the driving device, a speed device for controlling the working speed of the driving device, and a detection device for detecting the working state of the driving device; the driving device comprises a driving motor, and a connecting device for connecting the driving motor and the steps; and the connecting device is a reducing gear. According to the energy-saving automatic escalator, the working speed of the variable frequency motor of the escalator is adjusted according to the states of the passengers on the escalator; when no passenger is on the escalator, the power supply frequency of the motor is reduced so as to reduce the energy consumption of the motor; when no passengers use the escalator for a long time, the motor is turned off. |
