There is something called a shunt contact, which turns each section or stator of the linear motor into a brake, using eddy currents. This is a fail-safe system, in that when the power is lost, the shunt contactor closes immediately as it is a normally closed contact, hence is closed by a spring and opened with power. There is one shunt contact per stator, every meter or so, hence a failure of an individual contact by it failing to close, is not an issue. This has been on roller coasters for over a decade. It will not stop the elevator completely, but it will drop very slowly. With eddy currents, the more the kinetic energy involved via gravity, the greater the generated braking force. There will be either friction brakes in certain positions, or a nitrogen charged shock absorber at the bottom of the shaft to stop the cabin completely. control power can be maintained via a UPS battery for opening and closing the doors, the same system for emergency lighting and fire alarm systems.
@@jjhatch69 this could probably have been demonstrated with a model using a battery and automotive relays instead of having a professional bullshitter refer to proprietary diagnostic software and motioning to visit the observation deck.
So all this space they save the give it away to the digital twin and observation deck
Amazing !
Doesn't this elevator/lift also go sideways? probably need a new word(s) for this. It doesn't just go up.
the one that goes sideways is called a Tram
Good
what happens if the power goes out?

@@jjhatch69 great explanation!
@@jjhatch69 could you help me make something like what’s in the video?

Bingo!
🤣 Hope the price pool has a better quality than this.
But with this scripted train wreck winning was hardly a challenge.
