    How can I accurately calculate the inertia of rotors with cooling fins?

    Sorry for the double post Does this make sense, Torque = I*a I=moment of inertia a= Linear accelleration Angular accelleration a=r*x r= radius of shaft x= rad/s^2 T=I*x I=T/x So if I have a chord & wrap it around the shaft & suspend a "known weight"-mass on this & release it, I...

    How can I accurately calculate the inertia of rotors with cooling fins?

    I would like to be fairly accurate as they will be used to measure torque. Is their a site or an explanation of the spin rig proceedure anywhere on the internet prefferably with some formula's etc. No CAD at this stage! Thanks

    How can I accurately calculate the inertia of rotors with cooling fins?

    I have attached a drawing of one rotor, their is one of these at each end of a shaft with roller bearings in between. They are steel, heavy, & about 460mm diameter. I need to know the Inertia of these Rotors etc. Yes, Moment of Inertia Thanks

    How can I accurately calculate the inertia of rotors with cooling fins?

    Hello Everyone, I'm new hear & am hoping that someone can help me out. I have two Rotors, one on each end of a shaft with bearings in the centre, both have air cooling fins in the centre of each rotor. I need to calculate the Inertia of these Rotors, I have looked at several formula's but...
