Zusammenfassung:	The present invention relates to a technique capable of generating a steering reaction while minimizing a steering difference when a main motor for forming a steering reaction is failed. According to the present invention, disclosed is a steering reaction device of a steer-by-wire system, comprising: a first motor and a second motor providing a rotational force; a planetary gear apparatus selectively inputted with the rotational force from the first motor or the second motor, and generating the steering reaction by outputting the rotational force to a steering wheel; a braking means for selectively braking a rotational element of the planetary gear apparatus connected with the first motor and the second motor; and a controller for providing a signal to operate or not to operate the braking means when the first motor or the second motor fails. 본 발명은 조향반력 형성을 위한 주모터의 페일 발생시, 조타 이질감을 최소화하면서 조향반력을 생성 가능한 기술에 관한 것으로, 본 발명에서는, 회전력을 제공하는 제1모터 및 제2모터; 상기 제1모터 또는 제2모터로부터 선택적으로 회전력이 입력되고, 그 회전력을 스티어링휠에 출력하여 조향반력을 생성하는 유성기어장치; 상기 제1모터 및 제2모터와 연결된 유성기어장치의 회전요소를 선택적으로 제동하는 제동수단; 및 상기 제1모터 또는 제2모터의 페일시, 상기 제동수단을 제동 또는 해제 작동하기 위한 신호를 제공하는 제어기;를 포함하여 구성되는 스티어 바이 와이어 시스템의 조향 반력장치가 소개된다.
