Piezo actuators are electromechanical “motors”, based on the solid state piezomechanical deformation effect of piezoceramics (PZT lead zirconium titanate). Highlights are unlimited positioning sensitivity (sub-nanometers), high load capability, and high force generation, resulting in ideal mechanical dynamics with reaction times down to microseconds. Only piezo actuation allows top innovations in mechatronics like nano-positioning or high pressure common rail fuel injection.
Piezoelectric actuators are at an important stage of development into a large component market. Market pull is generated by large demand for ultra-small scale precision motion devices used in manufacturing and inspection equipment, high volume, low cost auto-focus assemblies required in phone cameras, and high volume, moderate cost ink printing cartridges used in printers; and partly by demand for micro actuator medical tools used in minimally invasive surgery and micro-grippers required in manufacturing micro-sized objects such as stents; and partly by dynamically-driven high temperature actuators for diesel injector valves in automobiles. Cost, yield and reliability are important concerns for each of these six applications. A number of these concerns relate to basic material science issues in the manufacture of the piezoelectric actuators for these targeted, diversified applications.
This report also deals with ultrasonic motors (USMs) that belong to the class of piezoelectric motors. In this work, the term “USM” will be used for the motor only (in other words, power electronics and closed-loop controls are not included). The system composed of the motor, power electronics, and closed-loop control will be called the ultrasonic actuator or piezoelectric actuator. The working principle of these motors has been well known for at least 50 years. However, they generated widespread interest only with the influential work of Sashida in 1982. Before that time, piezoceramic materials with high conversion efficiency and fast electronic power control of ultrasonic vibrations were not available.
Due to their specific advantages compared to conventional electromagnetic motors, USMs fill a gap in certain actuator applications. A key advantage of USMs over electromagnetic motors is their compactness, i.e., their high stall torque-mass ratio and high torque at low rotational speed, often making speed-reducing gears superfluous. Additionally, with no voltage applied, an inherent holding torque is present due to the frictional driving mechanism. It is also notable that their compactness and the high frequency electrical excitation make quick responses possible. USMs also offer a high potential for miniaturization. These actuators produce no magnetic field, since the excitation is quasi-electrostatic.
STUDY GOAL AND OBJECTIVES
This study focuses on key piezoelectric-operated actuators and motors and provides data about the size and growth of these markets, along with company profiles and industry trends. The goal of this report is to provide a detailed and comprehensive multi-client study of the markets in North America, Europe, Japan, China, India, Korea and the rest of the world (ROW) for piezoelectric-operated actuators and motors, as well as potential business opportunities in the future.
The objectives include thorough coverage of underlying economic issues driving the piezoelectric-operated actuators and motors business, as well as assessments of new, advanced piezoelectric-operated actuators and motors that are in development. Also covered are legislative pressures for more safety and environmental protection, as well as users’ expectations for economical actuators and motors. Another important objective is to provide realistic market data and forecasts for piezoelectric operated actuators and motors. This study provides the most thorough and up-to-date assessment that can be found anywhere on the subject. The study also provides extensive quantification of the many important facets of market development in piezoelectric-operated actuators and motors. This, in turn, contributes to a determination of the kinds of strategic responses companies may adopt in order to compete in these dynamic markets.
Users of piezoelectric actuators and motors in developed markets must contend with twin pressures – to innovate and, at the same time, to reduce costs. New applications, such as piezo fuel injectors, ink cartridges in printers, micro-pumps, micro-grippers, and micro-surgery tools for piezoelectric actuators and motors, have been proposed in recent years. This study condenses all of these business related issues and opportunities.
The piezoelectric actuator and motor market is an attractive and still-growing multi-million dollar market characterized by very high production volumes of actuators and motors that must be both extremely reliable and low in cost. Growth in the market continues to be driven by increasing demand in camera phones for auto-focus mechanisms, data storage, semiconductors, micro-electronics production, precision mechanics, life science and medical technology, optics, photonics, nanometrology, robots, toys, HVAC control systems, and other applications such as piezo fuel injectors, ink cartridges in printers, micro-pumps, micro-grippers and micro-surgery tools.
The piezoelectric-operated actuator and motor industry is complex and fast moving, with manufacturers increasingly adopting a truly global view of the market. Around the world, consumers are demanding a high power density as well as extremely long cycle life. Against this difficult background, manufacturers have attempted to achieve growth through company mergers and acquisitions, and by implementing global strategies. Piezoelectric-operated actuators and motors, once a technological novelty, have now entered the mainstream and are showing significant sales volumes.
iRAP conducted this study in 2007. However, with increased demand for these devices, and with improved and emerging technologies as well as applications, iRAP felt a need to conduct a detailed study and update technology developments and markets. The report identifies and evaluates piezoelectric-operated actuators and motors and technologies which show potential growth.
The report covers technology, product analysis, manufacturers’ profiles, competitive analysis, raw material suppliers, electronic suppliers, system integrators, material and material cost analysis, market dynamics and patent status of leading players ,to provide a complete picture of the status and growth of the piezoelectric actuator market on a global scale from 2009 to 2014.
This study provides the most complete accounting of the current market and future growth in piezoelectric actuators and motors. The study also provides extensive quantification of the important facets of market developments in emerging markets for these actuators and motors, such as China.
