1. An electronic brake system, comprising:
a motor comprising a first winding and a second winding;
a piston coupled to the motor through a power transmission member;
a cylinder configured to accommodate the piston, and comprising a first chamber and a second chamber partitioned by the piston;
a flow path coupled to the first chamber and the second chamber;
a control valve provided on the flow path;
a first inverter configured to supply a current to the first winding;
a second inverter configured to supply a current to the second winding; and
a processor configured to control the first inverter, the second inverter and the control valve, based on an output of a pedal displacement sensor,
wherein the processor is configured to open the control valve based on identifying a failure of at least one of the first winding, the second winding, the first inverter or the second inverter,
wherein, when the failure of the at least one of the first winding, the second winding, the first inverter or the second inverter is not identified, the processor is configured to close the control valve.
