Don't get me started on a simple 3 story condominium here in Calgary that uses a hydraulic Otis Elevator that is constantly shut down for service which is a major inconvenience for less able bodied people that are forced to stay indoors especially people in wheel chairs who live alone and cannot use the stairs!
Really nice triplex group! The controller system is fascinating, I really like the UI. Also having all the real time data directly on screen with so much info about I/O and even the voltage and current of the DC drive system is outstanding. I feel that most modern day controllers are no where near this convenient.
little bit obsolete configuration. i had seen many elevator machine rooms, but none of them had DC motors. each had 3 phase Induction motors with Windings 2 and 8 poles. (2 pole for fast level switching and 8 pole for the level correction) even the older ones from early 60.s. Last application of DC motors i had seen in Locomotives from 1991(class 163 of Czech Railways or Regiojet 162), or in a Paper Mills.
Worm shaft immersed in oil is best solution for longevity, although the DIY oil collector is a must 😃 Sadly, manufacturers do not produce sturdy stuff anymore
Reminds me of the transmitter site at wrtn in Yonkers New york. We had black suit all over everything because of the arcing from the motor brushes on the elevator systems nearby.
Thats some Heavy Duty equipment right there. Very cool. Thanks for posting this.
Been there do that but in England 😉🇬🇧🇬🇧🇬🇧🇬🇧
I love mods that put in SCR drives instead of taking out the motors and putting in boring VF drives and AC motors. They sound really cool as well!
Not many still around. Less and less understand them.
Thanks for watching.
@@OneDayWandersSCRs make amazing sounds!

That worm gear looks pretty worn out.
Just a bit. 😆

Thanks for the comment.
They have a newer controller with a slick interface. I'll try to get some of it.

Such a cool DOS-looking interface! No LEDs, no 7-segments.
Yes, Wyse 60 dumb terminal to see ASCII graphics.

Yes, the worm should be half submerged in oil. 🤷♂️

DC motor?
Yes, reused original motors during this modernization.
WOW ! ! !
I very Much Liked This Video Thank You .
Thanks for watching. I didn't expect anyone would find them.
Это двигателя на лебёдках с фазным ротором переменного тока ??
All DC. Stationary fields and DC armature with commutator for carbon brushes.
Sounds just like a Low-rise Otis Lexan elevator at 24 Greenway Plaza
Would have been something to see the old Haughtons
I didn't either. In 1996 they were already escentric controllers from Texas. BAXCO.
I believe the original was a model 5 evc.
Thank you for the detailed video! 👍
Tks. Hopefully, more, better to come .
