ANCO now offers servo-motor driven tables with frequency capacity as high as 400 Hz.  High torque direct drive servo-motors, acting through a link and spherical bearings, can thrust a few hundred to a few thousand pounds, over several inches at up to 100 ips, with good control over 1-250 Hz.

ANCO configures a family servo motor driven tables with table sizes from 12” x12” to 6’ x 8’, and payloads from 20 to 2,000 pounds.  Peak acceleration capacities are in the 2-20 g range.

ANCO’s tables are used for BSR and durability testing, seismic qualification, and ship/aircraft motion/vibration simulation. These designs are the result of ten years of development by ANCO, who recently demonstrated the ability of ANCO tables to reproduce broad band random and sinusoidal type wave forms up to 400 Hz with RMS error on the order of only 5%.

These high frequency studies were carried out as part of ANCO’s teaming with LMS, producer of multi-axes digital control systems for MAST systems.
