Electro-dynamic shakers play an important role in environmental testing. It provides a testing platform for product vibration testing in cases of design and type test, packing and transportation, reliability mission profile, fatigue test and more real-world environmental simulation. These tests are widely needed among most of industries, from automotive to IT, from household electrical appliances to satellite, from civil to defence labs.

The working principle of electro-dynamic shaker is that the shaker armature is moved in a magnetic field under electromagnetic force, which is generated by the interaction between driving current and magnetic flux. Therefore, we can get a wide range of vibration force by changing the driving current, the larger driving current, the higher force.

ECON presents customers EDM series electro-dynamic shaker with years experiences and optimized design, which is a better choice for customers to conduct vibration tests.

Calculation Formula of Excitation Force

F=M*a=(M0+M1+M2+...)*a
F  Excitation Force (kgf)
M0  Amature mass (kg)
M1  Extending table (kg)
M2  Specimen/UUT(kg)
a   Acceleration (g)
