SUMMARY

The discussion centers on the required torque and force for oscillating a metal circular bar at 50 Hz, with calculations indicating a minimum torque of 2.352 Nm and a force of 58.824 N. The project involves collaboration between mechanical engineers (MEs) and electrical engineers (EEs) to utilize induced currents for achieving the necessary torque and force. The operational environment is expected to reach temperatures between 150-200°F, and space constraints are a consideration. Participants discuss the feasibility of tuning mechanical properties to achieve resonance at the desired frequency, which could significantly reduce torque requirements.

PREREQUISITES
  • Understanding of torque calculations and mechanical properties
  • Knowledge of induced currents and their applications in electromagnetism
  • Familiarity with resonance in mechanical systems
  • Basic principles of thermal effects on material performance
NEXT STEPS
  • Research methods for calculating induced currents in electromagnetic systems
  • Explore techniques for tuning mechanical properties to achieve resonance
  • Investigate materials suitable for high-temperature environments (150-200°F)
  • Learn about torque and force requirements in oscillating systems
USEFUL FOR

Mechanical engineers, electrical engineers, and project managers involved in the design and implementation of oscillating systems requiring precise torque and force calculations.

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 :-p) . 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.

TTT Any help please?
 
Is there a chance to tune the mechanical part properties to have resonance at the desired frequency (50Hz)?
If you can do it - your torque needs would be reduced significally...
