I calculated that the motor should get up to speed within 4 seconds, but this value is made up and to be honest it will be used only in very rare cases. The machine will mostly be used to continuously cut in every 10-20 second or so, so it shouldn't be a problem to get the flywheel back to full...

According to my rough calculations 4kJ should be enough, for the strongest materials.

Thanks for the tip about dog clutches. This was completely new term for me. I originally had an eye on these types of clutches (https://www.mwmfrenifrizioni.it/en/electromagnetic-toothed-clutches-positive/esb-z.html). I'm not sure if these work completely in the same way as dog clutches. Also...

Thank you all for your answers. I haven't done calculations regarding this kind of machines before, so if there is some info that you need and I didn't provide, please let me know and I will do my best to provide it.

Yes, this is on point. I started the whole design based on eccentric punch presses.

The flywheel has been spun for t (4s) amount of time and has reached its peak kinetic energy (Ke) of 11kJ. Do I not need to take this in account, when the clutch activates and forwards the energy from the flywheel to the 2nd shaft where the cutting tool is located? This is all just speculation...

Hey everyone, I have a problem with sizing a clutch for my machine. My problem is, I don't know how to calculate the needed value (Nm) for the clutch to withstand the torque affected by the flywheel. I have a flywheel that weighs 90kg and is 600mm in diameter. It is rotating at 500rpm...
