Air-cooled electrodynamic shaker ES series

Short description
MIL-STD-810G specifies environmental test methods; the ES electrodynamic vibration shaker series reproduces transport and operational vibration and shock profiles and is designed to support MIL-STD-810G Method 514 as well as IEC/ISO/ASTM vibration standards.

Product overview
IEC/ISO/ASTM electrodynamic shaker system for three-axis (X/Y/Z) sinusoidal, broadband random and classical pulse shock response spectrum testing. Built with a double-magnetic-circuit armature, linear-guided roller bearings and trunnion isolation. Applicable for research laboratories, certification bodies and material R&D working with electrical appliances and industrial components.

Features → Benefit (selected highlights)

• 51 mm peak-to-peak displacement — enables large-amplitude, low-frequency shock profiles without reconfiguring fixtures.
• Wide frequency coverage up to 3,500 Hz — meets broadband random vibration requirements under MIL-STD-810G Method 514.
• Double-magnetic-circuit design — reduced flux leakage and stable coil temperature for continuous operation.
• Quick-mount VT/LT expanders — allow vertical and horizontal tests on the same bench.

Supported excitation modes

• Fixed frequency (steady-state)
• Sweep (linear or logarithmic)
• Sine (sinusoidal excitation and resonance dwell)
• Random (broadband)
• Shock (half-sine, trapezoidal, saw-tooth pulses for SRS testing)

System composition

• Electrodynamic shaker — air-cooled armature.
• Power amplifier — switching low-distortion output.
• Vibration controller — DSP closed-loop control for sine, random and shock.
• Head expanders & fixtures — standard or custom interface plates matched to DUT.
• Cooling system — low-noise blower for continuous operation.
