The invention discloses an electric steering mechanism. The electric steering mechanism comprises a motor, a linear displacement transfer device and two position feedback units. Each position feedback unit comprises a position sensor in transmission connection with a motor rotor, and a motor is directly connected with the linear displacement transfer device without adoption of a speed reducer to drive the linear displacement transfer device to move. When the motor is in loss of power, a manual part can be inserted to the rear portion of the motor to directly drive the motor rotor. Each position feedback unit is designed in a dual-redundancy feedback structure, and a screw nut, a roller screw or a planetary roller screw serve as the linear displacement transfer device. The electric steering mechanism further comprises a guide mechanism, and a roller linear guide rail with a vibration damping slider serves as the guide mechanism. The electric steering mechanism has the advantages of high bearing capacity, high reliability, quietness, miniaturization, convenience in maintenance and the like, and a goal of complete electrification of ships can be fulfilled.
