   Design of a Lamb's wave generator using amplified piezoelectric actuators
By C. Vloebergh; F. Labrique; D. Grenier [View]
[Download]

Abstract: This paper describes how to design a linear piezoelectric motor based on Lamb’s wave propagation along a metal rod of finite length. The Lamb’s wave is generated by controlling the oscillations of multi-layer-array amplified piezoelectric actuators supplied by half bridge PWM amplifiers. This motor can be used as a demonstrator in a laboratory on piezoelectric motor principles.

   Development of a miniaturized ultra sonic motor gate driver
By M. Jang; E. Chen; S. Iosef; G. Bailak; F. Dawson [View]
[Download]

Abstract: This paper describes the operating principles of a miniaturized gate driver for a Shinsei USM60 Ultrasonic Motor (USM). The proposed driver consists of the following blocks: control algorithm execution, speed calculation and task assignment, push-pull converter, USM piezo-deflection signal detection, frequency generation, gating signal generation and communication between the PC and the gate driver. Changes in control parameters and control strategy are facilitated through a Graphical User Interface running in a Labview environment. Control algorithm execution, event tasking, setpoint selection and speed/position calculation are executed by a PIC microcontroller. Gating generation and frequency generation are performed by a field programmable gate array (FPGA) and a frequencysynthesizer integrated circuit respectively.

   Analogous circuits for lossy piezoelectric ceramics
By G. Poulin; E. Sarraute; F. Costa [View]
[Download]

Abstract: This paper presents an innovative 1D model of piezoelectric ceramics, through the example of a thickness-mode piezoelectric disc. This model is dedicated to simulation of piezoelectric transducers. A special attention has been payed to the modelling of losses. Different frequency representations of mechanical losses have been compared using PSpice simulation tool, showing a good agreement with experimental results.

   Self-driving of a travelling wave ultrasonic motor: application to an active stick
By F. Giraud; B. Lemaire-Semail [View]
[Download]

Abstract: Even thought Travelling Wave Ultrasonic Motors use an other way of energy conversion than electromagnetic machines, the inversion of the Causal Ordering Graph of a simplified modelling, based on the assumption of the “ideal rotor”, highlights the need of a self driving of the actuator, in the same way of the classical synchronous machine. This self driving is then experimentally tested on a force feedback stick, because this application needs high torque and low rotational speed.

   Supply for piezoelectric actuators: a survey on existing and optimised structures
By C. Henaux; M.Budinger; B.Nogarede [View]
[Download]

Abstract: Today, in the field of high torque low speed actuators, centimetric piezoelectric drive constitute products with highly attractive functionality for Home Automation, Optics, Aeronautics, Space and Bio-medical Engineering. But the constraints inherent to the supply of rather capacitive armature piezoelectrics which works under the high voltage at ultrasonic frequencies, need to consider again classical supply usually used for magnetic actuators. So this paper presents a survey of classical and optimised supply for the main type of operating piezoelectric actuators.
