The invention discloses an electric steering gear. The electric steering gear comprises a driving motor; the input shaft is in transmission connection with a steering wheel and the driving motor, and a plurality of first transmission gears are arranged on the input shaft; the torsion bar shaft is provided with a plurality of second transmission gears and a plurality of electric control actuators, the first transmission gears and the second transmission gears are meshed in a one-to-one correspondence mode and form a plurality of gear sets, and the transmission ratios of the gear sets are different; the output shaft is in transmission connection with the torsion bar shaft; and the controller is electrically connected with the driving motor. Wherein the controller can control the electric control actuator to mesh the corresponding second transmission gear with the torsion bar shaft according to a signal acquired by the sensor so as to drive the output shaft to rotate and enable the output shaft to output a corresponding torque value and a corresponding rotation angle value, so that the power is not lost, and the power of the motor is utilized to the maximum extent.
