Bellissimo vide, ben realizzato ET ben esplicato. Avete anche vido dei vecchi ascensori, magari quelli con le portine di legno e con la porta principale che si apre con la chiave?

I'm guessing these are DC geared SCR controlled motors. I noticed that Otis puts the isolation transformer inside of the controller which I think is a really bad idea because if the transformer fails, it could destroy the entire controller. I have seen new Otis controllers with the transformer mounted separately. The blue boxes appear to be the DC ripple filters.

Yes, these are DC geared SCR controlled motors. We still have similar at E411 elevators. Transformer is present - no any problems fo 25 years.
