摘要： An acuator for a shift-by-wire system includes a druve motor installed inside a motor housing, the drive motor having a drive shaft, and a decelerator inside a decelerator housing coupled with the motor housing, the decelerator coupled to the drive shaft. The decelerator includes a sun gear connected to a first side of an eccentric part of the drive shaft, a ring gear engaged with the sun gear and fixed to the decelerator housing, an output shaft connected to a second side of the eccentric part, a first bearing coupled to one side of the eccentric part and supporting the sun gear, a second bearing coupled to the other side of the eccentric part and supporting the output shaft, and a power delivery unit coupled to the sun gear and the output shaft in a center region between the first and second bearings.

摘要： The present disclosure provides a shift by wire (SBW) driving actuator capable of improving control performance and durability through control of a brushless direct current (BLDC) motor by an inductive sensor, and improving gear transmission efficiency by introducing a multistage teeth-shaped transmission unit configured to connect a sun gear and an output shaft of a reducer to transmit a rotational force to reduce a load resulting from eccentric rotation of the sun gear.
