Patent ID: 7671513

Claim:
Motor ( 1 ) comprising: a guide; a stator, mounted for linear displacement along the guide, the stator including a stator face; a rotor ( 6 ), the rotor guided for rotation (R) around an axis (X) with respect to the stator, the stator face contacting the rotor; two clamping means, each clamping means capable of selectively establishing an engagement between the guide and the stator; and a plurality of longitudinal actuators, the actuators being essentially parallel with the axis and with the guide, the actuators controllable for i) activating one of the clamping means and displacing the other clamping means, then activating said other clamping means and displacing said one clamping means, thereby to generate said linear displacement, and ii) bending the stator in a changing direction thereby to generate a rotating wave on the stator face contacting the rotor and generate said rotation (R).
