Featuring the high precision of a galvanometer and the compact size and reliability of a resonant scanner, a rotational voice coil motor stage uses a flexure bearing to create rotational translation.

BEI Kimco has released a voice coil actuator (VCA) for extreme precision applications in aerospace, clean rooms, laboratory instrumentation, and medical environments. It comes with a moving magnet and ...

HITHERTO there has been no successful elucidation of the mechanism by which torsion of single crystals occurs. We have now, however, established that in zinc the main deformation process is rotational ...
