How is power supplied to a Ferris wheel?

[vidya sagar]

How the wiring is given for giant/ferry wheel as it rotates. I don't belong to electrical fields. Curious to know.

hi there
welcome to PF

ferry wheel

ferry wheel as on a boat ? or ferris wheel as in a fun park ?

I'm going to assume initially that you are talking about a ferris wheel

usually large electric motors and gearboxes

The London Eye has air conditioned, lighted capsules.

I couldn't find how the capsule power connects. I suspect a slip ring or two somewhere. I wouldn't be surprised if it's a low voltage DC system for safety reasons.

They do have battery backup on board in case of power failure.

That would be my expectation tooIt appears as tho I may have mis-read the OP a bit

This doesn't indicate the voltage but does include a picture of one of the interface components:

I would suspect that the voltage would be dangerous to touch. There are 32 air conditioned pods with leveling servos attached as well as a significant amount of architectural lighting. Running this off of a touch safe voltage would require some unreasonable current that would cause the brushes to wear out in short order.

From rbelli1's link:

All the capsule systems require electric power. But power has to cross two rotating interfaces to enter the capsules (i.e. ground–wheel, and wheel–capsule) and so this is accomplished via duplicated bus-bar/slip-rings[.]
