Electrodynamic Testing Machine Offers New Capacities for Endurance Testing

ZwickRoell’s advanced LTM electrodynamic testing machine uses patented linear motor technology to carry out endurance and fatigue testing. The electromagnetic drive is oil-free and provides the perfect solution for materials that are sensitive to contamination. Additionally, the patented ventilation and cooling system ensures that thermal influence is kept to a minimum without any effect on room temperature.

The LTM range was earlier limited to capacities of 5 and 10 kN, but now the series has been expanded to include 1, 2, and 3 kN versions. The potential to add a temperature chamber or quasi-static torsion drive is the latest advancement in these machines.

The systems are suitable for the electronics and medical industries, thanks to their smaller load capacities. Standard applications include dental, hip, or joint implants, but these machines can also be used in any kind of industry. Furthermore, a low moving mass reacts rapidly to inputs, thereby leading to exceptional accuracy, precision, and positioning.

The LTM electrodynamic testing machines can be operated at speeds ranging from 1 mm/minute up to 1.5 m/second. A 60 mm piston stroke accommodates most of the test requirements. The system also includes an adjustable crosshead as well as a T-slot table to accommodate components testing.

Advantages of the LTM Electrodynamic Testing Machine

  • Highest level of safety
  • Ergonomic operation
  • Wide range of speed
  • High dynamic performance of up to 100 Hz
  • Flexible use of specimen fixtures and grips
  • Motor-driven traverse adjustment
  • Extra oil, pneumatic, or coolant is not needed

The LTM electrodynamic testing machines come with the intuitive testXpert III and testXpert R software, enabling both dynamic and static testing capabilities.
