Abstract: The present invention relates to a motor driving control system and a control method thereof. The purpose of the present invention is to provide a motor driving control system and a control method thereof, which may change electric current limiting logic, which is applied to a BLDC motor for a cooling fan, in response to an operating speed of the motor to stably protect the motor from an overload in a low-speed driving state as well as an overload in a high-speed driving state.
