Product Overview

ZwickRoell LTM Electrodynamic Testing Machine Linear Motor Dynamic & Quasi-Static Materials Testing Systems (1 kN to 10 kN) The ZwickRoell LTM series is an electrodynamic testing machine driven by patented linear motor technology. Designed as an oil-free, low-noise alternative to traditional hydraulic systems, the LTM excels at both dynamic fatigue testing and quasi-static materials testing. Its low moved mass enables precise cyclic performance under tensile, compression, and flexural loading. Spanning load capacities from 1 kN to 10 kN, the machine is widely adopted in cleanroom and laboratory environments—particularly across medical implant manufacturing, composite materials research, and small-component quality control. --- Key Features & Advantages * Oil-Free Linear Motor Drive: Eliminates hydraulic fluids, pumps, and external cooling infrastructure, drastically reducing operating costs, maintenance demands, and acoustic noise. * Dual Dynamic & Quasi-Static Capability: High dynamic responsiveness combined with a wide speed range allows seamless transition between high-frequency fatigue cycling and slow quasi-static tests. * Compact Frame with Long Stroke: Features a 60 mm piston stroke and motor-driven crosshead adjustment for quick adaptability across varied specimen lengths and test fixtures. * Integrated T-Slotted Platform: Standard T-slotted base allows rapid mounting of custom component fixtures, alignment systems, and environmental baths. * Safe Setup & Operator Protection: Features a dedicated setup mode with speed restriction to 10 mm/s in compliance with EN 60204-1, along with manual crosshead locking and LED status monitoring. * Dual Software Integration: Compatible with testXpert R for dynamic fatigue waveform parameterization and testXpert III for quasi-static tensile and compression testing. --- Technical Overview * Available Force Capacities: 1 kN, 2 kN, 3 kN, 5 kN, and 10 kN (Model variants include high-resolution HR configurations) * Drive Mechanism: Electrodynamic linear motor with low moved mass * Piston Stroke: 60 mm * Measurement System: Coaxial travel measurement system mounted in the piston rod near the specimen for precise displacement readings * Control Electronics: testControl II digital controller * Key Applicable Standards: ISO 18489 (Cracked Round Bar PE Pipe Testing), ISO 14801 (Dental Implants), ASTM F1717 / ISO 12189 (Spinal Implants), ASTM F382 / ISO 9585 (Bone Plates), ASTM F1800 (Knee Implants), ASTM F543 (Bone Screws) --- Target Applications * Medical Devices & Biomedical Engineering: Dynamic fatigue and durability testing on hip joints, knee implants, spinal stabilization systems, bone plates, screws, and dental prostheses. * Plastics & Fiber-Reinforced Composites: Fatigue life determination and Cracked Round Bar (CRB) tests on polyethylenes, polymers, and composite specimens. * Precision Components & Electronics: Dynamic testing on micro-switches, automotive chains, electrical connectors, and miniature structural components.
