New Brochure on Piezoelectric Ceramic Motors Released by Physik Instrumente

Share Article

Piezo equipment manufacturer PI (Physik Instrumente) has released a new 70-page brochure on piezo ceramic motors. The catalog explains the operating principles and physics behind each type of motor and lists applications along with technical data and drawings. Several different types of piezo motors – inertial motors, often referred to as stick slip motors, resonant motors and piezo-worm type motors (piezo walk, or steppers) are covered.

Several types of piezoelectric motors are now available, each one tailored to specific applications and requirements.

General Properties of Piezo Motors
All three types of piezo motors explained in the brochure are self-clamping at rest (no energy consumption, very high stability) and the technology is intrinsically non-magnetic and vacuum compatible. These novel motors and actuators are also available fully integrated in precision positioners from miniature linear stages to 6-axis Hexapods and Z/tip/tilt platforms.

Inertial Motors (Stick-Slip)
These piezo motors are very compact and economical. Their motion is based on a piezoceramic element that expands slowly and then retracts very quickly. Due to their small size they lend themselves to the integration into miniature positioning stages, such as linear and rotary positioners. PI’s latest generation achieves a breakthrough in speed – up to 10 mm/sec and provides forces to 10N.

Ultrasonic Motors (resonant piezo motors)
These piezo motors provide the highest velocities, typically from 100 mm/sec to 1000 mm/sec. Their motion is very smooth, and forces on the order of 5 to 15 N are typical.

Piezo Stepping Motors (PiezoWalk®)
These are the most complex of the three motor types. They are based on several preloaded actuators performing coordinated motion similar to the way humans walk. PiezoWalk® motors are very robust and can provide high forces to 800 N. In addition to a long-range step mode a high dynamics sweep / scanning mode is also available, enabling picometers of resolution and kHz range bandwidth.
