Flywheel like design??
(OP)
I have a small motor that spins at 20,000 RPM. I have attached a steel wheel that has a plastic rim and a steel tire. When I turn the motor on, there is a force that is acting against the motor that feels like it s a centrifugal force or something. What is the actual force known as?
Secondly, how does one determine the best wheel design, OD, ID Thickness to have this force be as much as possible with this motor?
Does a large OD with a small steel tire create greater force than a smaller OD with a larger steel tire?
I do hope I made some sense here and appreciate any input anyone may have.
Thank you,
Rudy

To an Engineer, the glass is twice as big as it needs to be.

And don't forget to analyse the thing for hoop stresses. 20krpm is pretty quick.

What kind of Mechanical Engineering do you do? Have you taken a look at the posting rules on Eng-Tips? We don't give college or tech. degrees in engineering here. Your's are some pretty elementary questions, but not a simple problem in practice, and all the more complicated if you can't use the correct terminology. Dig out your Dynamics, Strength of Materials, and Theory of Elasticity text books and get a little better handle on your problem. I don't think you will get good results with a steel tire and a plastic rim and hub. How are you going to fit this to the motor shaft and what keeps things from flying apart at about 10000 rpm?

Huh, yeah. Unless you have a high-speed spindle designed for such use, and with appropriate tool holders, and properly-balanced payload, you'll be getting a rude introduction to my friend "Mr. Bearing Failure." Tread lightly there, Sport.
