Electrodynamic Shaker with Vibration Controller and Power Amplifier
The mode of function of a shaker corresponds to that of a loudspeaker. The vibration movement is generated by the interaction of electric current passing through the plunger coil and a magnetic field. The force used to accelerate the moving element comprised of a ribbed body and the wrapped plunger coil is proportional to the coil current, the magnetic flux density, and the length of conductor in the magnetic field. The vibration level of shaker can therefore be controlled by electric current intensity.

Technical Parameters of Horizontal Expander:
Vertical electromagnetic shaker is unable to test the heavy and large specimen, and the high position of center of gravity will cause sideslip, tumbling and overturning moment and this will always overstress the suspension system of shaker and damage the system. Therefore, need for slip table system for vibration testing is increasing to allow the testing to be done horizontally so that the system can withstand larger
and heavier load.
