Disclosed is an actuator generating haptic sensations, the actuator having a spherical rotor driven by a magnetic force vector created around the same, a stator having a space corresponding in shape to the spherical rotor defined therein to allow the spherical rotor to be positioned in the space and having a portion of an upper part of the spherical rotor exposed, at least three rotation-driving coils formed in the stator at a given distance from each other to provide the magnetic force vector to the spherical rotor, and a driving unit independently controlling electric current supplied to each of the rotation-driving coils to create the magnetic force vector.
