Brochure covers novel piezo ceramic step linear motors
PI (Physik Instrumente) is publishing a new brochure covering its range of piezo ceramic linear motors. These are non-magnetic, vacuum-compatible and are claimed to achieve significantly higher forces and resolutions than other piezo motor designs, such as ultrasonic motors or inertial motors.
The PI linear motors are based on the patented PiezoWalk principle and achieve forces from 2kg to 60kg per actuator. They are available in two versions called Nexline (offering higher forces) and Nexact (which are smaller and faster). In addition to a long-range step mode, both also provide a very high dynamic sweep/scanning mode, enabling 50pm of resolution and kHz range bandwidth to be achieved.
These novel motor actuators are also available as drive systems in nanopositioning linear stages and multi-axis positioning systems, such as six-axis Hexapods or tripod Z/tip/tilt platforms.
Applications fields for these actuators include:
- Optics and photonics
- Aerospace
- Semiconductor alignment and test and measurement
- Precision motion control
- Microscopy
