Our piezomotors are available as both open-loop control (non-feedback control) and closed-loop control (feedback control) systems; and are offered in a variety of configurations (including non-magnetic). Piezomotors are Self-Locking Preloading the piezoceramic actuators against the runner ensures self-locking of the drive when at rest and powered down. As a result, it does not consume any power, does not heat up, and keeps the position mechanically stable. The piezoceramic actuator is excited with a high frequency electric signal (100 to200 kHz). The deformation of the actuator leads to a periodic diagonal moti Ultrasonic piezomotors dispense with the mechanical complexity of classical rotary motor/gear/leadscrew combinations in favor of costs and reliability. Piezo Inertia Drives Inertia Drives are space-saving and low-cost piezo-based drives with relatively high holding forces and a travel range that is only limited by the length of the runner.

The patented >> PiezoWalk ® Stepping Drives with their complex design consisting of longitudinal, shear and bender elements and corresponding contacts, are manufactured entirely at PI Ceramic. PIShift piezomotors Compact, cost-effective inertia drive (Stick-Slip). When at rest, the drive is self-locking and therefore requires no current and generates no heat. It holds the position with maximum force. Alignment of mechanical and optical components Stable alignment of optical paths. Home; Software & Accessories; Positioning, Support & Accessories; NANOPOSITIONING: Long-travel piezomotors ‘reboot’ the motion-control toolbox. Novel piezoelectric technology provides essentially unlimited travel distances, along with high axial force, exceptional speeds, compactness, and stable position-hold without dither—to control an array of formerly insoluble applications.

Other important patents in the early development of this technology include: "Electrical motor", V. Lavrinenko, M. Nekrasov, Patent USSR # 217509, priority May 10, 1965. Piezoelectric actuators and motors can be used in a wide range of applications, including haptic feedback, pneumatic valves, active controls and many others. Our bonding and packaging processes greatly improve the reliability and robustness of the piezo ceramics.

Piezomotors, presentation April 2, 2008 V. Lavrinenko, A. Tyshko Application of the piezomotors are based on the following properties 1. simplicity; 2. small size and small step – widely used for cameras, optical systems scanning and micromanipulators, minimal step may be in order of the fractions of angle second so piezomotor is considered the ideal positioning device; 3. high torque – up

small size and small step – widely used for cameras, optical systems scanning and micromanipulators, minimal step may be in order of the fractions of angle second so piezomotor is considered the ideal positioning device; 3. high torque – up piezomotors can now be used as practical alternatives to classic DC stepper motor combinations. The application described below provides a typical example of this. Ultrasonic piezomotors providean as yet unrivaled speed and acceleration for the latest total stations used in geodesy at high resolution and low power consumption. Ultrasonic piezomotors dispense with the mechanical complexity of classical rotary motor/gear/leadscrew combinations in favor of costs and reliability. Piezo Inertia Drives Inertia Drives are space-saving and low-cost piezo-based drives with relatively high holding forces and a travel range that is only limited by the length of the runner. Physik Instrumente GmbH & Co. KG has announced the U-521 ultrasonic piezomotors driven by ceramic motors.

Piezomotors are a form of electromechanical interface device that have unique properties with regard to response capability and proportionate control. They employ ferroelectric materials that undergo a lattice distortion when subjected to an electric field. This paper gives a brief review of materia GROUND BREAKING MICRO MOTORS.
