Danube Tower Elevator

A Great Video. Seeing the double decker cabins reminded me of when I used to repair e service lifts at Sydney Tower working for KONE. Looking at that controller it looked a lot like a TMS 900/9000. Interesting lay out. I really dig those hoist motors with air compressed brakes. Very rare to see as in Australia I have seen these very few times.

This motor is a BBC(Brown Boveri & co. AG, Baden, CH) 1964, 54kw DC motor with a seperate exitation. So as There are 2 voltages on the man. plate. the 200V is for the rotor, the 220V is for the exitor coils. The electronic controller is actually a thyristor-rectifier. Indeed it's built to convert the 3 phase AC in DC for the traction motor. I am an upcoming electrical technician. This one motor is visible in the 'Technisches museum' or technical museum in Vienna, Austria

1:51 check out those old slot-in cards! 6:48 that's one massive air-intake into the top of the traction machine. Is the noise at 6:45 related to those air compressors at 7:13 activating and deactivating the brake? I've never seen this type before, only electric. 7:53 Amazing! Would never happen in this day and age - risk asessments, etc. This is one great video - I used to have some from my old video camera, but accidently recorded over!!

Every time the motor slows down you can hear the distinct whine of the converter that transforms the AC mains power into DC for use by the motor. It's called a chopper. Many Japanese DC machines of the 1980s feature such.

i'm really sorry to say this: but that 'çhopper' is actually not a chopper: it is a thyristor-rectifier. Choppers are converting DC into variable voltage DC, to control motors. In this case this thyristor system is converting the AC into DC and also controlling the motor at it's own.

Wow! quite an interesting gear less traction machine 70HP it's Big! The shaft way is similar to the Turbo Lift hoist way in Star Trek T.N.G.

@Fletcher2244 ok, thanks

[@OctoSwift]

@Fletcher2244 Why??? modernize :(

[@OctoSwift]

How old is the motor?

[@Manuel13070]

Jamaal This her Motor is 25 years olf

[@Manuel13070]

Jamaal old

[@TheTheo58]

The original motor is still in service from 1964 be around 55 years old, I would have expected the traction machine to be using between 440-480 V DC 200 73 HP motor seems to be drawing a lot of current 330 amps at 200 V DC.
