JZQ series exciter is driven by power amplifier to convert electrical energy into mechanical energy. It uses permanent magnet material as the main body, with fan cooling, with large output, wide frequency range, reasonable structure, reliable and stable characteristics. The product can be used for environmental vibration and fatigue test of large and medium-sized instrument parts. The frequency and amplitude can be set freely to study the dynamic response, resonance frequency and mechanical impedance of the structure under test. It can also be used as a vibration table detection sensor.
