Abstract: A high performance MEMS scanner is disclosed. In some embodiments, scanner mirror has a wide and short aspect ratio that is similar to rotating polygon facets. Long torsion arms allow large rotation angles including 20° zero-to-peak mechanical and greater. Suspensions couple the scan mirror to torsion arms, reducing dynamic mirror deformation by spreading the torque load. “leverage members” at the distal ends of the torsion arms help reduce stress concentrations. Elimination of a mounting frame increases device yield. Heater leads allow for precise trimming of the scanner resonant frequency. A compressive mount holds mounting pads against mounting structures.

A first elastic member 12 and a second elastic member 22 are connected to the both ends of the flex movement member 1. The flex movement of the both ends of the flex movement member 1 causes distortion or bending in the first elastic member 12 and the second elastic member 22, so that a first frictional member 12 and a second frictional member 23 each serving as a contact section in contact with a lens barrel 5 move in a direction different from the flex movement direction of the both ends of the flex movement member 1. Thus, the lens barrel 5 is driven.

Abstract: The present invention provides a piezoelectric ultrasonic motors and a method of driving a motor with a standing wave. The motors include a thin ring/cylinder-type stator having one or two piezoelectric (ceramic or single crystal) rings/cylinders, coated with a segmented top/outer electrode and a bottom/inner electrode and poled in a thickness/radial direction, a metal ring/cylinder which is laminated with piezoelectric ring(s)/cylinder(s) having several inner threaded protrusions. The motor also includes a power source for supplying an alternating voltage to one group of electrodes of the piezoelectric stator to excite a standing wave vibration along one diameter direction of the stator ring/cylinder. The motor further includes a short cylinder rotor, which may have a lens inside for certain optical applications, or it may include other elements. The rotor is attached to the stator at the threaded surface of the protrusions and is driven to produce a circular motion, which may also be translated into a linear motion by the threaded surface through standing wave deformation at protrusions. Reverse motion of the rotor can be realized by applying the alternating voltage to another group of electrodes of the stator.

The motor includes a stator having a piezoelectric ceramic disc polarized in the radial direction and bounded by a top electrode and a segmented bottom electrode. The motor also includes a power source for applying two pairs of alternating voltages to the bottom electrode segments to excite a shear-shear mode vibration in the stator, resulting in a shear-shear mode flexure traveling wave in the stator. The motor further includes a rotor operatively connected to the stator, and the stator is driven to rotate through a frictional force between the rotor and the stator due to the traveling wave deformation of the stator. A linear ultrasonic piezoelectric motor and method of exciting a flexure traveling wave to linearly drive the motor is provided. The motor includes a stator having a rectangular piezoelectric ceramic plate that is polarized in the longitudinal direction. The motor also includes a power source for applying two pairs of alternating voltages to the bottom electrode segments to excite a shear-shear mode vibration in the stator, resulting in a shear-shear mode flexure traveling wave in the stator. The motor further includes a slider operatively connected to the stator, and the stator is driven to move linearly through a frictional force between the slider and the stator due to the traveling wave deformation of the stator.

Abstract: A piezoelectric drive, especially a piezoelectric motor for producing continuous or stepwise movements, a friction element for such a piezoelectric drive as well as for transmission of forces between stator and rotor, and a circuit arrangement for operating a piezoelectric drive, especially a piezoelectric motor. An elastic double frame enclosing the transducer and having inner and outer frames is disposed at each outer node of the bending oscillation mode to hold the piezoelectric transducer and produce the pressing force of the friction element. The inner frame is joined to each of the longitudinal narrow sides of the transducer and the outer frame to the outer fastening. Further, the outer frame and inner frame are spaced apart and maintained in contact by stays or bridges. The friction element is constructed as a double-layer structure with a first hard, porous member joined to the transducer, and with a second part or member including an abrasion-resistant monolithic material maintained in contact with the rotor, the two layers being bonded by sintering. The circuit arrangement for operation of the drive relies on a special bridge power amplifier as well as on the capability of compensating for temperature variation of the drive for stable operation thereof.
