1. An electromechanical brake system comprising an actuator of an electromechanical brake operated by a motor, the electromechanical brake system comprising:
a motor driving unit configured to drive the motor; and
a control unit configured to be electrically connected to the motor driving unit,
wherein the control unit is configured to:
calculate a first rotation angle of a spindle rotated by driving the motor in a brake apply mode of the electromechanical brake,
calculate a second rotation angle of the spindle in a braking release mode of the electromechanical brake, and
when a difference between the calculated first rotation angle and the calculated second rotation angle exists, control a notification device to notify a wear state of a brake pad.
