The invention discloses an energy-saving escalator. Comprising a speed monitoring device, a displayer, a driving device, a handrail belt driving device, a step chain, a guide rail, a missing step detector, a supporting structure, a handrail belt inlet guiding device, a tensioning station, an operating element, a comb plate, an apron board, an escalator apron board light band lighting device, a handrail belt, a step, a baseboard, a controller and an auxiliary handrail belt steering section. The energy-saving control precision is improved, the control action feedback is accelerated and the energy-saving control efficiency is improved through real-time detection feedback and signal control of three current change points by the current transformer, the IGBT inverter reduces the control voltage and keeps the stable operation of the control circuit, the DC bus capacitor carries out power compensation on the inverter, the stability of the control circuit is improved, and the energy-saving control system is suitable for large-scale popularization and application. The reactor limits short-circuit current and higher harmonics and performs over-current protection on the whole circuit, so that the stability of the energy-saving process of the escalator is improved, the loss of a control unit in the energy-saving process is reduced, and the service life of the device is prolonged.
