Hi guys, I don't normally post in here as I am an ME. Anyways for a project, I am teamed up with a couple of ME, and some EE guys. We are working on a project that will involve oscillating a metal circular bar at quite high frequencies (50 Hz, I know that's not a lot for you guys, but we don't like to do stuff like that :tongue2:) . From my calculations, minimum torque required will be at least 2.352 Nm, and from the size of the shaft, a minimum of 58.824 N of force will be required to accelerate the shaft quickly enough. Now to the question, the electrical guys would like to accomplish this using induced currects and all that kind of jive that you guys do that I don't really understand so much. I guess my question is, is this a reasonable amount of torque and force to produce? The environment will be somewhat hot (~150-200°F at the most) and space will be somewhat limited. If this is indeed possible, how much voltage will be required? I know I'm making a lot of broad questions, so if you would like to help, just make some general assumptions about things that I have left out. Thanks a lot, and I appreciate the help.
