The M-660 PILine piezo motor rotation stage from Physik Instrumente (PI) enables customers to perform rapid positioning for applications such as microscopy and mass-storage solutions.

The high-speed U-164 PILine linear motors offer speeds of up to two rotations per second, with a maximum torque of up to 0.3Nm.

Direct transmission onto the ceramic friction ring makes the stage compact and self-locking when at rest, allowing loads of up to 1kg.

The M-660 offers unlimited travel, has a maximum velocity of 720o/s and is 15mm high.

Stage position can be controlled to 34 urad resolution using the direct metrology encoder and, in combination with the self-locking design, is said to provide significantly higher position stability than classical stepper or DC motors.

The stage has an aperture of 35mm, making it suitable for the positioning of transmitting optical components, and it can be combined with PI linear stages to build a compact multi-axis system.

Physik Instrumente

PI is a global manufacturer of high precision positioning systems and products based on piezo technology. Used in markets as diverse as biotechnology, semiconductor, defence and astronomy, PI’s products work to improve the speed and precision of many cutting edge processes. Actuators, sensors and positioning systems with either sub-micron or nanometre level precision; many customised for the end user, are included in the product range.

With manufacturing and subsidiary offices around the world and a workforce of more than 500 PI provides direct local support where it is needed. Products range from component level piezo ceramic assemblies to six axis hexapod positioning robots. PI manufactures its own piezo ceramic material including multilayer devices that incorporate its patented ceramic insulation technology. Lead free ceramic technology is now also included in the company’s product range. With the flexibility and continuity of supply offered by having control of piezo ceramic production comes security and speed of delivery for customers who rely on or are looking to move into this area of technology. PI’s piezo ultrasonic and step drive motor technologies offer unique performance including self-locking capability, high force or high speed and non-magnetic and vacuum compatibility.
