  • Patent number: 11515761
    Abstract: 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.
    Type: Grant
    Filed: May 29, 2020
    Date of Patent: November 29, 2022
    Assignees: KYUNG CHANG INDUSTRIAL CO., LTD, SAM HYUN CO., LTD.
    Inventors: Ki Cheol Hyun, Kyu Jung Kim, Dae Yeon Kim, Jin Heo, Tae Keuk Choi, Jeong Seok Kim
  • Patent number: 11441675
    Abstract: The present disclosure provides an inhibitor integrated actuator shift control device capable of controlling a position of a gear shift by improving control performance and durability through position control of a brushless direct current (BLDC) motor by an inductive sensor, forming a metallic uneven portion on an output shaft flange part of a reducer, and detecting a variation amount in induced current due to the metallic uneven portion.
