When I went to pick up my lathe last week I had to drive past a damn with a small hydro-electric plant attached. I'd been thinking about Japanese mag-lev trains on the way and wondered if the shaft that holds the turbine (pretty clueless here) couldn't be mounted in a similar way, so that its spins suspended in a magnetic field to create a totally frictionless piece of equipment, could it even be mounted in a vacuum chamber? I wonder if more electricity would be generated?
Not so crazy at all, similar...
Not so crazy at all, similar has been done but not until now is it begining to work well, I wouldn't have thought centering the shaft would be a problem but it seems it is.
"While the promise of virtually frictionless, oil-free, active magnetic bearings (e.g., a maglev compressor) has been around since the 1940's, reliable electronic control for maintaining a motor shaft within required microscopic tolerances was not available until recently. Today's nanosecond-fast semiconductor devices have overcome the maglev shaft-centering challenge."
Could you explain further?...
Could you explain further? Or have any observations on maglev trains, like monorails it all seems so good but nothing ever comes of it. I'm an engineering dimwit
I did read a while ago about a new train system being planned for Tehran...will try and find more info,
