摘要： The present disclosure relates to a power swivel device for preventing spacing or jamming caused by individual component tolerances, assembly tolerances, accumulated tolerances, environment, etc. and may include a fixing base installed in a body or a seat of a vehicle; a rotary plate rotatably installed on the fixing base and on which a driven gear part is formed on an inner surface or an outer surface; a variable actuator device which swivels and rotates the rotary plate relative to the fixing base by utilizing a drive gear engaged with the driven gear part of the rotary plate, wherein position of the drive gear is variably installed relative to the fixing base; and an elastic pressurization device for elastically pressurizing the variable actuator device such that the drive gear is elastically pressurized in a direction to the driven gear part.

摘要： The present disclosure relates to a rotation angle sensing system and method of swivel core that enables recognition of an accurate standard position of a rotor, may include a rotation sensing device installed on a stator of the swivel core and sensing rotation state of a rotor of the swivel core; and an identifier formed on the rotor to generate a sensing signal of the rotation sensing device, wherein the standard position of the rotor can be calibrated or initialized by only one rotation sensing device, thereby decreasing the number of sensors to be installed, reducing installation cost or manufacturing cost and accurately sense a standard position by forming a hill part as an identifier on the inner surface of the rotor.
