The linear motor testing machine - an all around machine for the small force range

The LTM is an electrodynamic testing machine with a drive based on linear motor technology. The drive concept developed and patented by ZwickRoell enables the LTM to be used for both dynamic tests and static materials and components testing. The low moved mass of the drive provides ideal conditions for performing fatigue tests with tensile, compression, and flexural loading.

The LTM is available with loads of 1 kN, 2 kN, 3 kN, 5 kN and 10 kN.

The LTM electrodynamic testing machine is used in industries where oil-free and low-noise drive technology are preferred, for example, in the medical industry for standard-compliant testing of hip joint, knee, or dental implants.

Other typical application examples include fatigue and durability tests on standard specimens made of plastics, fiber composites and metals.

For components testing, the LTM is equipped with a T-slotted platform that can be adapted to components, and test fixtures quickly and easily as standard.

Intuitive operation via our testXpert R and testXpert software makes the LTM a genuine all-rounder for industrial purposes, and for applications in research and as part of university curricula.

Maintenance-free operation


  • High dynamic performance due to low moving mass
  • Wide speed-range enables dynamic as well as quasi-static tests
  • Low operating and maintenance costs with oil-free drive technology without additional supply feeds
  • Motor-driven traverse adjustment for convenient operation
  • safe setup mode as per EN 60204-1 via speed reduction to 10 mm/s
  • Simple manual crosshead locking via hand lever with electrical monitoring and LED status indicator
  • Long piston-stroke (60 mm) enables wide variety of applications
  • Operator-friendly testXpert R testing software with preset controller settings and availability of free controller definition for dynamic testing requirements
  • Intelligent testing software testXpert III featuring intuitive operation for static testing requirements.
  • Flexible use of specimen grips and fixtures over the entire dynamic product range
  • The electromagnetic drive was designed specifically for the speed range relevant to testing technology and features exceptionally quiet operation, optimum control quality and extremely high positioning accuracy
  • The travel measuring system is coaxial to the test axis and mounted near the specimen in the piston rod, enabling high positioning repeatability and precise piston travel measurement

Test frequencies

The test frequencies, which are up to 100 Hz depending on the test, ensure short test times and with that high specimen throughput.



The linear motor does not require any additional media connections such as for pneumatics, coolant or oil. This lowers maintenance and installation costs.



Operation is via testXpert R testing software for dynamic tests and testXpert III for static tests. It is intuitive and specifically adapted for the test tasks.
