An electronic brake system includes: a reservoir in which a pressurized medium is stored; a hydraulic pressure supply device comprising a first pressure chamber provided in front of a hydraulic piston and a second pressure chamber provided at a rear of the hydraulic piston, and configured to generate a hydraulic pressure by moving the hydraulic piston forward or backward; a hydraulic control unit configured to control a flow of the hydraulic pressure transferred to a wheel cylinder from the hydraulic pressure supply device; and a controller configured to control the hydraulic pressure supply device and the hydraulic control unit, wherein the hydraulic pressure supply device comprises a motor having a plurality of separate system windings for moving the hydraulic piston, and a control valve configured to open and close a flow path that communicates the first pressure chamber and the second pressure chamber, and when a portion of the plurality of separate system windings of the motor fails, the controller is configured to open the control valve to push the hydraulic piston so that a portion of a hydraulic pressure discharged from a pressure chamber is transferred to another pressure chamber.
