Model Number: KPD-303(1271)

This machine operates on the principle of electromagnetic excitation, creating a free vibration system with an experimental spring and mass block. It drives the system into vibration via electromagnetic force, reaching resonance for testing purposes. Compared to traditional electromagnetic fatigue test machines, this unit employs cutting-edge control and measurement technologies. It precisely measures the spring compression and feeds back the information to the control system. The control system utilizes electromagnetic resonance, pulse width modulation, and closed-loop control techniques. After a rapid adjustment during the startup phase, the entire machine quickly enters a stable resonance state as set by the amplitude. It boasts advantages such as quick startup, accurate amplitude, stable process, and broad application range. Consequently, for springs requiring high-frequency fatigue testing, the testing process is significantly time and energy-efficient, and testing costs are greatly reduced.
