Dear All, Good Day! I have a Rotor which is used for medical centrifuge application ( separation max of 2ml. x 12 slots) need to find out the Frictional Torque of the Rotor ( rotor made up of Alu 6061 shape conical). weight of the Rotor is 0.370 Kg. need to find out Mass moment of Inertia of the Rotor. Rotor Maximum RPM is 16000. What are the other parameters needs to be considered when we design Rotor. Any one could help me out on this. Thanks in advance, Regards, Rex.
Hi Naga, I have no specific knowledge about medical centrifuges - but if you have a look at the MS Power Point presentation below - you will see you need more information about the substance you are trying to separate in the centrifuge - than you have provided in your original posting. So I think it is a bit more involved than you had perhaps first thought - but I hope this helps you with your problem. https://www.google.co.uk/url?sa=t&r...nA4aqFqG24cYtZgyA&sig2=s_ebOx4Ocu6RtkT-m3TMIQ
Hi Naga, If I understand, you want designed a centrifugal rotor, ok. By Frictional Torque I understand you want to calculate the sum of the resistance your medium on rotor with 16000rpm. That is right? The moment of Inertia it is simple to calculate for not complicated shape, but if you had a complex model there is a another method - calculation the moment of inertia with for example SolidWorks. I am waiting for your answer. KKA
