Abstract: A single piezoelectric is excited at a first frequency to cause two vibration modes in a resonator producing a first elliptical motion in a first direction at a selected contacting portion of the resonator that is placed in frictional engagement with a driven element to move the driven element in a first direction. A second frequency excites the same piezoelectric to cause two vibration modes of the resonator producing a second elliptical motion in a second direction at the selected contacting portion to move the driven element in a second direction. The piezoelectric is preloaded in compression by the resonator. Walls of the resonator are stressed past their yield point to maintain the preload. Specially shaped ends on the piezoelectric help preloading. The piezoelectric can send or receive vibratory signals through the driven element to or from sensors to determine the position of the driven element relative to the piezoelectric element or resonator.

Abstract: A piezoelectric apparatus comprising a piezoelectric element that is held in static compression is manufactured using moldable materials and a molding process, e.g., injection molding or die casting. The static compression is caused by an intrinsic urge of the moldable material to expand, contract, or deform otherwise, which develops in the material during the hardening phase of the molding process. To enhance the usefulness of the device, a variety of inserts can be connected to the device and various features can be formed by the moldable material at the same time as the molding process takes place. Static preloads may also be caused by mechanically preloaded elements that are introduced during the molding process or by elements that concurrently introduced but that are permanently deformed thereafter.

During the service life of the motor and resonator at least one operating state variable changes, and the change in operating variable is used to help avoid failure of the piezoelectric motor.

Abstract: The invention relates to a piezoelectric motor comprising a piezoelectric component that is connected to a resonator and a two-dimensional resonator that interacts with a movable element, the resonator having principal surfaces that are parallel to each other and that are also identical in shape and size. The invention further relates to methods for producing such piezoelectric motors, wherein the resonators are manufactured by cutting a profiled, extruded bar into lengths or by cutting, preferably by punching, from sheet metal having constant thickness. Finally, this invention relates to a method for exciting such a piezoelectric motor, wherein the excitation frequency or frequencies is/are generated by the control electronics as a function of time in response to the respective peak current and/or in response to the respective phase minimum between current and voltage and/or in response to the change in phase.

Abstract: A piezoelectric system has a piezoelectric motor (20) driving a driven element (22) so as to move the driven element (822) in response to an electric signal (25). The motor (20) has at least a first optimal operating frequency at which the motor (20) moves the driven element (22) an amount that meets predetermined criteria. The motor (20) and driven element (22) have a desired performance criteria when operated at that first operating frequency. A plurality of concatenated sinusoidal sweeping frequencies are repeatedly supplied to the piezoelectric motor (20) with at least one of the sweeping frequencies being sufficiently close to the first operating frequency to cause detectable motion of the driven element (22). The frequencies are varied in response to movement of at least one of the motor (20) and the driven element (22) to produce an average performance of the motor (20) and driven element (22) for a time corresponding to the time for one sweep of frequencies.
