Abstract
An electromechanical brake and an operating method thereof are disclosed. According to an aspect of the present disclosure, there may be provided an electromechanical brake including: a piston which is provided to be capable of advancing and retreating to press a pad plate; a power conversion unit including a spindle which rotates by receiving a driving force from an actuator, and a nut which is connected to the spindle and advances or retreats by rotation of the spindle in a first direction or a second direction; and a positioning portion which is screwed with a thread formed inside the piston, receives a rotational force from a drive motor, linearly moves according to rotational movement, and adjusts a relative position of the piston with respect to the power conversion unit, wherein the positioning portion includes a first screw provided on an outer surface of one side of the nut and having, on an outer peripheral surface, a first thread that meshes with the thread, a second screw provided on an outer side surface of the other side of the nut and having, on an outer peripheral surface, a second thread that meshes with the thread, a first gear provided to rotate together with the second screw by receiving the rotational force from the drive motor, and an interlocking member provided between the first screw and the second screws to interlock and linearly move the first and second screws by the rotation of either the first screw or the second screw and adjust a relative position with the piston.
