A method for detecting a motor error of a motor driven power steering (MDPS) may include: calculating, by a control unit, a Q-axis command current of a motor through a Q-axis command current calculation unit, according to requested torque; calculating a command current of each phase of the motor from the calculated Q-axis command current of the motor; controlling the motor according to the Q-axis command current of the motor, and sensing a measured current of each phase of the motor through each current sensor; determining whether each phase of the motor is disconnected, through the command current and the measured current of each phase of the motor; and outputting the determination result to an output unit.
