China Electric Vibration Test Bench - High Eccentric Load Resistance Multiple Protections Suppliers, Products

An electric vibration test bench built to withstand high eccentric loads, boasting multiple protective mechanisms. It delivers precise vibration simulation to assess components’ performance and durability under dynamic stress scenarios.

Product Description

Product Features
1. The dual magnetic circuit structure results in high magnetic field strength and low magnetic leakage; The special demagnetization structure can reduce the leakage magnetic flux of the table to below 1mT.
2. The skeleton free dynamic coil designed with dynamic optimization not only reduces the mass of moving parts but also increases the first-order resonant frequency, broadening the upper limit operating frequency.
3. The rocker arm suspension dynamic coil system has high resistance to eccentric loads.
4. Built in support inflatable leather bowl with good low-frequency characteristics.
5. The ear shaft adopts a combined rubber spring vibration isolation device to reduce ground dynamic vibration.
6. Comprehensive protection: overheating, overload, overcurrent, overvoltage, displacement, phase loss, current limiting protection, soft start, and short circuit protection.
