Model: PLG Series Description: This series of electromagnetic resonance fatigue testing machines are used for fatigue tests of metal material and components under tension, compression or reversal load. If relevant grips are provided, three-point bending test, four-point bending test, tension and compression of sheet sample test and circle test, gear wheel, bolt, connecting rod, roller chain, crackle expanding test can be available. The series of electromagnetic resonance fatigue testing machines feature an optimized design and a rational structure. The automatic controlled system adopts an advanced and wide-pulse-control system and a new-type of power amplifier to improve the reliability of the electric system. The electromagnetic resonance fatigue testing system is with high efficiency, easy and non-stop shake, low energy consuming, accurate control, and small fluctuation. The machines comply with DIN50100.
