The linear motor testing machine - an all around machine for the small force range
The LTM electrodynamic testing machines are used to determine the durability of materials and components in the finite life fatigue and high cycle fatigue ranges.
The LTM’s wide speed range allows it to be used for both dynamic fatigue tests and quasi-static tests. The oil-free drive, combined with ease of installation, makes the electrodynamic testing machine ideal for use in biomedical engineering and electronics, as well as for research and training. Typical examples include tests on hip-joint and knee replacements and dental implants. Other applications are tests on standard plastics and composites specimens, as well as aluminum and plastics CT and SEB specimens.
The electrodynamic testing machine is available with loads of 1, 2, 3, 5 and 10 kN.
