Piezoceramic Components and Actuators

PI Ceramic offers a wealth of experience in the manufacturing of piezoceramic materials, components and actuators. The piezoceramic materials can be adapted individually to perfectly fit the later use of the piezo components. Lead-free piezo ceramics are available for the construction of sensor components. Actuators made of piezo crystals provide a hysteresis-free linear displacement.

Piezoelectric Drives

Depending on the configuration and control, piezoceramic actuators can be used to create translational motions or as motors with a virtually unlimited travel range. The choice of drive depends on the requirements of the application.

Electromagnetic Drives

Electromagnetic Drives

Rotating electric motors such as DC or stepper motors are used in connection with screw or worm drives. Stepper motor systems with high-resolution encoders can perform minimum incremental motions of 10 nm with high reliability and repeatability.

Parallel Kinematics

Parallel Kinematics

In a parallel-kinematic multi-axis system, all actuators act directly on a single moving platform. This means that all axes can be designed with identical dynamic properties, thus reducing the moved mass considerably. Hexapods are used for moving and precision positioning, aligning and displacing loads in all six degrees of freedom, i.e., three linear and three rotational axes.

Sensor Technologies

The linearity and repeatability achieved are not possible without highest-resolution measuring devices. Accuracies in the range of a few nanometers and below require a position measurement method that can also detect motion in this range.

Controllers / Software

Controllers and Software

Fast settling or extremely smooth low speed motion, high positional stability, high resolution and high dynamics – the requirements placed on piezo systems vary greatly and need drivers and controllers with a high degree of flexibility.

PI Motion Control
Guiding Systems

Guiding Systems and Force Transmission

Flexure joints, mechanical guide components or magnetic bearings? Which kind of guiding system PI uses in its products depends on parameters such as travel range, required precision, load, lifetime and ambient conditions.
