Abstract
Disclosed is an actuator of an electronic brake system including: a motor having a stator and a rotor for generating a rotational force by an electrical signal, the rotor having an accommodating space therein; a power conversion unit disposed in the accommodating space, and including a spindle rotated by a rotational force of the rotor and a nut coupled to the spindle to be linearly moved by rotation of the spindle; a piston coupled to move with the nut; and a sleeve coupled to one end of the rotor by a bearing so that the rotor is relatively rotatable and having an inner space communicating with the accommodating space and accommodating the piston so as to be able to move forward and backward.
