Abstract
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.
