Piezo motion specialist Physik Instrumente (PI)
(Auburn, MA) has added a new member to its
PiezoMove family of motion-amplified, flexure-guided
piezo linear actuators. Weighing in at 4 g, the new P-
604 PiezoMove linear actuator provides long-travel in
a small package. Features include:
A large displacement of 300 µm.
An open-loop resolution of 0.5 nm.
An unloaded resonant frequency of 900 Hz
with a tolerance of ±20%.
A footprint of only 20 x 13 x 4 mm.
A multilayer piezo element.
A lifetime of 100 billion cycles.
Smooth Rotation Applimotion (Loomis, CA) offers many of its brushless direct drive motor kits and assemblies for vacuum applica- tions. The linear arc, LARC, motor kits work with large diameter and low-profile applications with through-hole require- ments. Features include: Zero cogging for smooth rotation. Availability with laser welded stainless enclosures. Applicability from 200 mm up to >1 m diameter. A modular nature that allows them to integrate into
Worm Gear Speed Reducers New 80:1 and 100:1 ratios are now avail- able in single reduction 700 Series worm gear speed reducers form Boston Gear (Charlotte, NC).Features include: Projecting, quill, or coupling input options. ■
