A linear actuator assembly (100) has a linear actuator including a motor shaft (104) extending from a base (24) with a piezoelectric component (28) which oscillates the shaft (104). The shaft (104) has a faceted surface. A movable carriage (16) has a notch (40) with at least one flat surface that receives the shaft (104) of the linear actuator. The carriage (16) is in direct and continuous contact with the motor shaft (104) at the notch (40) such that the motor shaft's facet is in contact with the flat surface of the notch (40) when the carriage (16) moves linearly along a travel axis (20). A spring (42) is coupled to the carriage (16) to urge the motor shaft (104) into contact with the notch (40) of the carriage (16) so as to maintain contact between the motor shaft's facet and the flat surface of the notch (40) to inhibit rotation of the motor shaft (104).

Die vorliegende Erfindung betrifft zunächst eine Anordnung zum stoßwellengeführten Bewegen eines Objektes (01), insbesondere zum Justieren dieses Objektes (01) gegenüber einem als ruhend angesehenen Objekt (03). Die Erfindung betrifft im Weiteren ein Verfahren zum stoßwellengeführten Bewegen eines Objektes (01) mithilfe der erfindungsgemäßen Anordnung. Die erfindungsgemäße Anordnung umfasst einen am zu bewegenden Objekt (01) angepressten Stoßgeber (04), welcher eine Mehrzahl an übereinander angeordneten piezoelektrischen Elementen (06) umfasst. Die Anordnung umfasst weiterhin eine Ansteuerelektronik zum Ansteuern der piezoelektrischen Elemente (06) zur Generierung einer Stoßwelle im Stoßgeber (04).
摘要:
A system for contactless transmission of energy and control signals between a primary device and a secondary device. The primary device has a primary set with at least one primary coil and an electronic supply driver for supplying primary signals to the primary set of primary coils. A secondary device has a secondary set with at least one secondary coil, at least one piezoelectric actuator, and electronic components including a resonant circuit powered by the secondary set. The piezoelectric actuator is powered and controlled through the secondary set of secondary coils and the electronic components.

An inertial drive actuator includes a displacement unit 3, a vibration substrate 4, a first magnetic field generator 11 which generates a magnetic field, a movable body 10 which is disposed on a flat surface of the vibration substrate 4, and which includes a first yoke 9 that concentrates a magnetic flux of an N-pole and an S-pole generated by the first magnetic field generator 11, at a predetermined position, and a second yoke 12 which is disposed on a side of the vibration substrate, opposite to a direction facing the movable body 10. A movement in a direction perpendicular to a direction in which, the movable body 10 is driven is regulated mechanically by end portions of the second yoke 12 facing end portions of the first yoke 9 at an outer side of the vibration substrate 4, and a frictional force acting between the movable body 10 and the vibration substrate 4 is controlled by controlling the magnetic field generated by the first magnetic field generator 11, and the movable body 10 is driven.
