A switched reluctance motor and an initial activating method thereof in which an aligning pulse is applied to a stator in order to make a rotor wait at a normal torque generating region to be driven, thereby preventing the rotor from rotating in a direction reverse to a target rotating direction. The standby position of the rotor in the switched reluctance motor is sensed. When the standby position of the rotor corresponds to a reverse torque generating region where a torque causing rotation in a direction reverse to a target rotating direction is generated, an aligning pulse is applied to the stator, thereby causing the rotor to rotate to a normal torque generating region where a torque causing rotation in a normal direction corresponding to the target rotating direction is generated. A driving pulse is then to the stator, thereby causing the rotor waiting at the normal torque generating region to rotate in the normal direction. Accordingly, it is possible to stably and reliably control the rotating direction of the motor. In addition, there is an advantage in that the durability and reliability of the appliance using the motor according to the present invention can be improved.
