Electrodynamic Shaker
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.
Major Sub Systems of the Electrodynamic Shaker are:
Our armature features a web structure to minimise weight, while maintaining structural integrity. The pattern can only be casted, therefore, in order to achieve the best quality, we import these castings from one of the world’s most renowned sources. Complete tooling, milling, drilling, and tapping of these castings is performed in our in-house CNC centre located in Noida, India.
The winding process is carried out at our headquarters in Roorkee, India. Industrial grade epoxy is used to ensure that the coils adhere to each other as well as the magnesium structure. Air cooled systems use a solid copper conductor for superior conductivity and water cooled systems use hollow aluminium conductor for weight reduction.
For an air cooled system, power is transferred to the armature coil using highly flexible copper ropes. For a water cooled system, power and water are transferred on the same line using highly flexible copper ropes and hose pipes, respectively. Only oxygen free copper is used to ensure long life of the conductor and the rope.
