HectorWhile you are here, can I pick your brain?What do you know of the Samsung type motor experiments?These motors have a lot in common with your out runner ideas of several years ago, I believe?
True, there are funny tricks going on involving a computer, much like kids racing drones, where this generation of hot riders are happening.The other trick is pulsed DC of some 400 volts very accurately delivered at very specific moments in time to each phase.I know pulsed DC is a force to contend with, having it shear off a 5/16" spine hardened motor shaft with the torque delivered by a fist sized motor, from standing start to a locked shaft.A 24 volt motor on 350 volts of pulsed DC stayed cool in spite of twisting off the shaft.Anyway let me know what you think about the Samsung magicCheers Waren

My goodnessCan we ever get into funny obscure topics of engineering here on this forum? Next we are going to hear about rubber bearings that the shaft rides on a film of water much like a water skier slips along the surface of that fluid. After wooden bearings, vessels have been using rubber for more than half a century, and now plastic, to ride on the continuous exchange of the fluid, water pumped through the space between the shaft and bearing, not unlike the magnetic bearings so fondly mentioned for some devices shafts to ride on.Air, yes, of course, even air is a fluid. Those massive stage sets moved soundlessly across the stage floor, like the magic they are to watch, ride on air casters, a silent cushion of compressed air, not unlike a toilet plunger.( watch ₩out for fart sounds)
So when your wife says" let's go and see an opera" say " what a great idea!" You might be very surprised by what is being done with physics.You have to admit that making "magic" beats making war, if you are playing with the edges of physics. Humans are a strange, and complex species.Cheers Warren

At Bagnell Dam in Missouri the generator armatures that are 30' across are running on redwood down in the bottom and the water running through keeps them cool and lubed. I believe it was finished in 1929.
