Vibration System

Miniature vibration table PMG2000

Application

The PMG series miniature vibration table is a compact portable broadband vibration device with permanent magnet, which is characterized by its small size, light weight, high excitation force, portability, durable structure and convenient operation. The miniature vibration table is composed of a drive coil, an excitation table, a roller guide, air bag support assembly, and a magnetic circuit. The system is equipped with DPS series power amplifier, which is with features of high efficiency, high performance and low noise.

 

Industry application

  • Large working table;

  • Permanent magnet design, the system is lightweight and portable, with excellent energy-to-volume ratio;

  • The product series has complete specifications, wide thrust range selection, and wide frequency range;

  • Silent mode and forced air cooling are optional to ensure on-site operating performance requirements;

  • Perfect system detection and protection functions.

 

Typical application

  • General vibration test;

  • Fatigue performance test;

  • Scientific research and teaching demonstration;

  • Dynamic response measurement.
