ABSTRACT:
Switched reluctance motor and an initial activating method thereof in which an aligning pulse is applied to a stator to make a rotor wait at a normal torque generating region to be driven, 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, 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, causing the rotor waiting at the normal torque generating region to rotate in the normal direction.
