Abstract: PURPOSE: A system and a method for preventing overheat of a motor for an electric power steering system are provided to prevent a motor from being overheated in advance because current is restricted in a range of predetermined current limit steering angle. CONSTITUTION: A system and a method for preventing overheat of a motor for an electric power steering system comprises a motor current control unit and an overheating prevention unit. The motor current control unit controls current applying to a motor. The overheating prevention unit is controlled by the motor current control unit in order to restrict amplitude of the current applying to the motor. The overheating prevention unit recognizes the current applying to the motor periodically, and sets a steering angle range based on the applied current. The overheating prevention unit receives steering angle signals of a vehicle which an electric power steering system is applied. If current steering angle is included in a range of the current limit steering angle, the overheating prevention unit controls the current applying to the motor.
