High - Force Shakers Vibration Testing Machine With CE Certificated For Big Payload

High - Force Shakers Vibration Testing Machine With CE Certificated For Big Payload

Introduction:

Firstly, all of our shakers are electrodynamic shakers. They rely on the same physical relationships that make a loudspeaker work. Basically, when a current passes through a wire that is in a magnetic field, a force perpendicular to the wire and to the magnetic flux is induced in the wire. The amount of force is proportional to the current, to the magnetic flux and to the length of wire in the magnetic field. We wind the wire around a cylindrical coil form that is part of the shaker armature and elastically suspend it in a radial magnetic field. This results in an axial force acting on the armature in proportion to the applied current. The suspension holds the coil concentric within the magnetic field. It allows the armature to move a limited distance axially relative to the shaker body. This limited distance is termed the shaker’s displacement stroke.
