PURPOSE: Location correction method of a Hall sensor of a BLDC electric motor using reverse electromotive voltage and BLDC electric motor supporting the same are provided to reduce vibration and noise by decreasing torque ripple. CONSTITUTION: A motor includes stator and rotor. Hall sensors (120) detect a location of a rotor of the motor. A motor control unit (130) controls driving of the motor. A memory stores a location correction value. An inverter (150) supplies power required for the motor driving. [Reference numerals] (130) Motor control unit; (140) PWM driving unit
