Closing the loop on a V8 piezo linear motor with a laser interferometer: resolution down to 0.15 nanometers is achievable. Here's how it works: https://www.pi-usa.us ...

Linear motors are proliferating. They give machines the absolute highest precision and dynamic performance. Linear motors are very quick and precise for positioning, but are also capable of slow, ...

Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...

They are installed not only in electrical linear motors, but also in pneumatic, hydraulic, ball-screw or power-grip belt drives and wherever high-accuracy, dynamic positioning tasks must be performed.

A series of linear stepper motors can provide constant positioning force to 400 N over full travel lengths of 300 mm. The Saia ULE Series is available in unipolar or bipolar configurations and can ...

To run a stepper motor smoothly, it's necessary to apply linear acceleration. However, conventional algorithms to generate linear acceleration require complicated mathematics, which makes it difficult ...

Designed for high-end applications in bio-nanotechnology, fiber-optics, microscopy, semiconductor testing, and metrology, the Physik Instrumente (PI-USA) N-565 linear positioner offers 0.5-nm system ...
