Design, concentricity and Accuracy
are three important parameters in case of magnetic bearings. The rotor of the
magnetic bearing is fitted with a Sapphire ring jewel or a Graphite bush, which
has a cup cavity in the front to guide the entry of the pin. This eliminates
damaging of the pin during assembly and easily guides the pin inside the hole of
the jewel/Graphite bush during assembly.
Minimum numbers of components are used in the assembly, 3 components for the
stator and 2 components for the rotor in order to maintain concentricity of the
magnets with respect to the center.
The metal pin is deep fitted into the holder to allow some spring action of the
pin during assembly. The pin is rounded on the edges and highly polished.
Virgin Brass rods are used in making the components. |
