Other AbstractThe utility model belongs to the field of excavators and particularly relates to an all-electric servo excavator, which comprises an operating mechanism, a slewing mechanism and a travelling mechanism. The slewing mechanism is relatively rotatably mounted on the travelling mechanism. The operating mechanism is hinged to the slewing mechanism. The operating mechanism, the slewing mechanism and the travelling mechanism are driven by independent servo motors respectively. A control cabinet for powering every servo motor is arranged on the slewing mechanism. The servo motors are electrically connected with the control cabinet. Oil cylinders, hydraulic motors and a hydraulic system, belonging to existing excavators, are omitted from the all-electric servo excavator, the servo motors are used as the power source and are used with a screw mechanism and a gear mechanism for driving, and accordingly intermediate conversion of energy is omitted, and energy can be effectively economized. The all-electric servo excavator needs no engine, so that pollution and noise are reduced.
