I'm not an electrical engineer or anything related to that subject, so my apologies if I understood something incorrectly.
Well, I read somewhere that the slower the railgun is, the higher its efficiency, so I was wondering: if it is slow enough, you could use it as an actuator?
Either in linear action, rotating or even using flexible rails/wires simulating artificial muscles.
Since the railgun works using lorentz force, I tried to find lorentz force actuators in the shape of rails, but I could only find Voice Coils actuators. And whenever I search for those, their efficiency is below 1%.
In any case, I was trying to find out what should be the amperage and voltage for a Lorentz Force rail linear actuator, but I couldn't find any answer and I even tried to ask ChatGPT.
Which said that in order to move a 3000kg weight at 2m/s with 90% of efficiency, I would need 1000 amps, 200 volts and rails with 0.1 of capacitance while having around 10mm to 30mm of diameter.
Obviously, I don't even know how to calculate/test how true is this affirmation.
