Extremely straight and flat motion, or multi-axis motion with accuracy requirements in the sub-nanometer or sub-microradian range.They are used when requirements like the following need be met: Guided piezo actuators (1 to 6 axes) are complex nanopositioners with integrated piezo drives and solid-state, friction-free linkages (flexures).

PiezoWalk® linear motors can achieve the highest forces along with picometer resolution, however velocity is limited from 1mm/sec for high force devices and up to 15mm/second for the new V-8 PicmaWalk drives. Ultrasonic resonant motors provide a wide dynamic range from microns/second and below to 100’s of mm/sec. Piezo Inertia motors (stick-slip) are most compact and simple with relatively low forces of 1N to 10N and speed to 10 mm/sec. All piezo motors are intrinsically non-magnetic, vacuum compatible and self-locking at rest. Piezo Motors are based on different drive principles optimized for high force, high speed, minimized dimensions and cost. They typically consist of one or more of piezo elements driving a runner. Piezoelectric motors require more complex drive electronics and can provide long travel ranges (up to 100’s of mm). They provide short travel ranges typically under 1mm. Traditional piezo actuators expand analogous to the applied drive voltage. Piezo motion devices are often divided into two groups: actuators and motors. Email our engineers if you have additional questions about using PI piezo motion products to solve your application problem. This tutorial includes an introduction to the piezoelectric effect, a discussion of the difference bewtween a piezo actuator and a piezo motors, an explanation of hybrid mechanisms, and a quick start guide to PI piezo motion products. Close contact between user and manufacturer is the best recipe for success.

PI provides a large variety of piezo actuator and piezo motor drive technologies, each one optimized for different parameters such as cost, precision, force, speed and size. To use the advantages of piezoelectric positioning technology to its full extent, it is important to carefully analyze the application in which a piezo drive or nano-positioning system is to be used. There is not one single type of piezo drive that works for every application. The demand for higher speed and/or precision in fields such as bio-nanotechnology, semiconductors, metrology, data comm, and photonics keep pushing manufacturers to come up with innovative drive technologies.
