Currently my Professor chose "the implementation of magnetic levitation technology for centrifuges" as a research point for my PHD. However, due to considerable lack of resources in my country, I can\t have enough research materials to start this research. So, I wish if anyone can aid me with research materials or recommend some website resources to start with.
Your comments and guidelines are more than welcome.
Hello Khaled,
I could indicate you onle Maglev technology for trains, not for centrifuges.
Regards.
In my opinion, maglev technology for centrifuges = use of magnetic bearings. Guess this is used already.
Using electromagnetic Levitation, one can lift the conducting material in air and using electromagnetic principle one can also rotate as well as heat the conducting substance without any physical contacts.
An electromagnetic levitation system or levitator is a coil system of two or more coils partially embedded in ferromagnetic core and excited by different voltage sources. The currents in different coils decides the mechanical stability.
Centrifugal force can be developed using axial flux induction motor.
What I foresee, is that it is a combination of electromagnetic levitator and axial flux induction motor acting both on slightly levitated conducting material by Electromagnetic levitator and rotation is caused by axial flux Induction motor.
More details can be obtained in internet by searching electromagnetic levitation .
The useful book may be
E.R.Laithewaite, Special Purpose Induction Machines
S.A. Nasar & I. Boldea Linear Motion electric Machines (initial edition of the book)
The scheme may be useful for non contact separation of electrically conducting ore.

I would really appreciate if you have any submittals about the Maglev traction technology
@Henri Cloetens
I know magnetic bearing can be a magnificent idea but I wonder If I can utilize the linear motor Maglev tech. To drive and elevate the centrifuge rotor.
@Rakesh Kumar Srivastava
Many thanks for your much appreciated contributions
Lift of material is using Levitating coils on the GROUND.
Now you need to rotate so as to cause centrifuge. Linear motor will be of no use. One has to use axial flux induction motor whose active surface is facing the top of lifted material.
I think it is clear

My colleague in the Mechanics department informed me that I can use Compressed air/turbine system to reach an extremely high speed, and I guess have a frictionless bearings using maglev tech in a vacumed chamber would benefit alot.
I think i can induce heat on the material surface of the centirefuge.
However I am very worried about the limitations for the fabrication and the assembly of such instrument..!
