The invention relates to an electric servo ultrahigh-pressure system and an operating principle thereof. The electric servo ultrahigh-pressure system comprises an oil pump motor set, an oil tank, a pressurizer, an oil cooling device and a water filtration and pressurization device which are mounted on a framework, wherein the oil pump motor set comprises a pressure sensor and a servo driver mounted in an electrical cabinet; the pressure sensor is mounted at an oil outlet of the oil pump and is used for monitoring the oil pressure of the system in real time; and the servo driver is connected with the pressure sensor through a cable and sends an instruction to control the rotating speed of a servo motor according to a signal detected by the pressure sensor. By the adoption of the form that the servo motor drives the oil pump, the pressure fluctuation generated by the reversing of the pressurizer is reduced, so that the output pressure value of high-pressure water is more stable, the quality of a workpiece incis
