    • 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).
    • 线性致动器组件(100)具有线性致动器,该线性致动器包括从基座(24)延伸的电动机轴(104)以及使轴(104)摆动的压电元件(28)。 轴(104)具有刻面。 可移动的托架(16)具有凹口(40),其具有至少一个平坦的表面,该平坦表面容纳线性致动器的轴(104)。 滑架(16)在凹口(40)处与马达轴(104)直接和连续地接触,使得当托架(16)移动时,马达轴的小面与凹口(40)的平坦表面接触 沿着行进轴线(20)线性地。 弹簧(42)联接到滑架(16)以促使电动机轴(104)与滑架(16)的凹口(40)接触,以便保持马达轴的小面与平面之间的接触 所述切口(40)用于禁止所述马达轴(104)的旋转。

    • 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.
