Electrodynamic Shaker（Water-Cooling）

Application

 

1.JOEO Water-cooling Electrodynamic Shaker are commonly used for larger payloads and more demanding structural test applications. By utilizing dual hydrostatic bearings, payloads with high overturning moments can be tested without the need for an external guidance system.

2.Water-cooling Electrodynamic shaker produces a relatively low noise output and requires less demand on the facility's HVAC system. JOEO water-cooled Electrodynamic Shaker is completely sealed, making it ideal for clean rooms and hazardous environments.

3.Electrodynamic shaker（Water-cooling）has large force, strong bearing capacity and high cooling efficiency，Redesigned for optimal cooling capacity, the efficient parallel water cooling design contributes to excellent overall reliability of our systems. Our new parallel cooling design uses separate closed loops on the armature coil, the excitation coil, the copper ring and the body for optimal cooling capacity
