Abstract
Disclosed is an actuator of an electronic brake system including: a drive unit generating a power and including a motor having a stator and a rotor; a piston unit operated by the drive unit and including a piston reciprocating in a bore chamber provided in a piston housing to contain a fluid; a power transmission unit having one end coupled to the rotor and the other end coupled to the piston to convert a rotational motion of the rotor into a linear motion of the piston; a sensing magnet coupled to the power transmission unit to rotate along the motor; and a motor position sensor disposed coaxially with and spaced apart from the sensing magnet to sense a position of the motor based on the rotation of the sensing magnet.
