Summary: Sdyn’s SEV and SEW series of Electrodynamic Shaker produces vibration based on the principle of magnetism. The SEV series is air cooled and SEW series is water cooled, respectively. The product portfolio covers all ranges of shaker, from 10 kgf up to 32000 kgf and beyond. An Electrodynamic Shaker has two separate coils, one is stationary and the other is dynamic. A stationary magnetic field is produced from the stationary or field coil inside the shaker body and a dynamic magnetic field is produced from the dynamic or armature coil winded on the armature. Interaction of these two magnetic fields causes the freely suspended armature to move. This principle of magnetism is based on Fleming’s Left Hand Rule.
