The electro-hydraulic servo drive has connected hydraulically reversibly controlled pump and executive hydro-cylinder with indicator of position of its rod connected through the first and the second integrators to the mechanism of control of the angle of turn of the control element, supplementary pump, indicator of angle of turn, tank and feeding valves, drive electric motor of the reversibly controlled pump, indicator of current consumption, restrictor-former, temperature indicator placed at the drive electric motor, this through transformer is connected to the control input of correction former. The output of the restrictor-former is through correction former connected in series to the input of the second integrator. The indicator of the rod position is the potentiometer transformer including potentiometer connected to the source of direct voltage, the first and the second diodes, the first and the second resistors, through those the first and the second outputs of the potentiometer, respectively, are connected to the source of direct voltage, the cathode of the first and the second outputs of the source of direct voltage, anode of the first and the cathode of the second diodes are earthed, the potentiometer slide is connected to the load.
