The present disclosure provides a steering feedback actuator having residual friction torque, the steering feedback actuator including a motor configured to provide feedback torque to a steering wheel, in which the motor includes a rotor configured to be rotated by supplied power, and a stator configured to surround the rotor, in which the stator is configured by stacking a plurality of electric steel sheets that is conductors, and in which when the steering feedback actuator is broken down, an iron loss of the stator is increased by adjusting a thickness of the electric steel sheet to generate residual frictional torque for ensuring traveling stability.
