Zusammenfassung:The present invention relates to a shift actuator of a shift-by-wire transmission for a vehicle. The shift actuator of a shift-by-wire transmission for a vehicle includes a driving motor. The driving motor includes: a stator having a housing space formed in a center part; a rotor housed in the housing space to be rotated through interaction between the stator and a magnetic force, while eccentrically rotated along a path spaced by an eccentric distance apart from an eccentric position; a deceleration part reducing the eccentric rotation speed of the rotor; and an output shaft rotated at the rotation speed reduced by the deceleration part. Therefore, since a driving mode of a transmission is controlled through the driving motor, the shift actuator of a shift-by-wire transmission for a vehicle is capable of accurately settling in the driving mode of the transmission in accordance with a switching operation of a user to guarantee the operational reliability of the transmission, and significantly reduce an occupied volume and weight in comparison to an existing actuator. 본 발명은 차량용 시프트-바이-와이어 변속기의 시프트 액츄에이터에 관한 것으로, 중앙부에 수용 공간이 마련된 고정자와; 상기 수용 공간에 수용되어 상기 고정자와 자력의 상호 작용으로 회전하되, 편심 위치를 중심으로 편심 거리만큼 이격된 경로로 편심 회전하는 회전자와;상기 회전자의 편심 회전 속도를 감속시키는 감속부와; 상기 감속부에 의해 감속된 회전 속도로 회전하는 출력축을; 구비한 구동 모터에 의하여 변속기의 운전 모드를 조절함으로써, 사용자의 스위칭 조작에 부합하여 변속기의 운전 모드에 정확하게 안착하여 변속기의 작동 신뢰성을 보장하고, 차지하는 부피와 중량을 종래에 비하여 크게 줄인 차량용 시프트-바이-와이어 변속기의 시프트 액츄에이터를 제공한다.
