Surface wave motor and method for displacing a movable element
A method for displacing a movable element ( 3 ) by means of at least two actuators ( 4, 5 ) facing each other on a stator ( 2 ). Electrical wave signals are simultaneously applied to at least two actuators facing each other so that oppositely directed waves are generated in the surface of the stator...

| Zusammenfassung: | A method for displacing a movable element ( 3 ) by means of at least two actuators ( 4, 5 ) facing each other on a stator ( 2 ). Electrical wave signals are simultaneously applied to at least two actuators facing each other so that oppositely directed waves are generated in the surface of the stator. The two oppositely directed waves form a compound wave in the surface of the stator by means of which the movable element is displaced over a moving area located between the actuators. |
