PURPOSE: A low speed mode control device of a BLDC motor and control method thereof are provided to compensate a measurement period at a low mode and to perform the accurate control of a BLDC motor. CONSTITUTION: A low speed mode control device of a BLDC motor(14) includes a hole sensor, a receiver, a low speed mode determining unit, a present speed operation unit, a parameter operation unit, a prediction speed operation unit, a controller and a BLDC motor. The hole sensor senses the location of a rotor and generates an edge signal. The low speed mode determining unit determines the low speed mode of the BL DC motor. The parameter operation unit computes the speed predictive parameter for the control cycle of the next BLDC motor. |
