A driving apparatus of a BLDC(BrushLess DC) motor is provided to prevent an overheat of the motor without stopping the motor by repeatedly reducing an output thereof with a certain ratio in case of the temperature to rise consecutively. In a driving apparatus of a BLDC motor, a motor includes a rotor and a stator. A power module supplies a power to the motor. A temperature sensor detects a temperature of the motor and the power module. A storing unit(30) stores the temperature of the temperature sensor. A control unit(16) compares the temperature detected by the temperature sensor with a reference value, calculates a temperature variation ratio within a certain time by using the temperature stored at the storing unit(30) and controls an output of the motor by using the same in a case of the motor to be determined as the overheated. |
