The electric requirements would stop you from putting it in your backyard.
The motor is 3 Phase around 150A. Residential areas are generally not wired to be able to offer 3P power to customers. You would likely need to rent some commercial space to be able to get the electric hookup.
If you didn’t run the lights, it’s only 33kW motor, less in newer Starships
Assuming you had 208V 3ph, that’s under 100A. Much less if you are in commercial area with 240V 3ph
If you don’t plan to spin 48 people, you could replace motor with a 120V single phase motor 5hp and remove a lot of weight from the ride (cut holes in every other fiberglass panel)
A decently small generator (relative to a full trailer carnival ride)… could power this. There are many tow behind 50kVA diesel generators. (Another $8k)
BTW the reason these UFO/gravs are for sale is because they are all rotting, the fiberglass panels that hold it together are like paper now and too expensive to repair.
Look what I really pay them for is for them to know and for me not having to. They say 3p, 3p it is, whatever gets the monkeyfunkin’ GRAVITRON spinning!!
Usually it’s the meter and the cabling that needs changing, like an extra phase needs to be introduced but it should be available at street level if any commercial place is around.
Your shop might have had the cables already and just needed the meter change.
VFDs are definitely the way to go, that’s what most enthusiasts used. When we did SirenCon over at Camp Tesumas in Wisconsin, we had a giant generator that we had to use to run the bigger sirens, especially the Cyclone 125 which has a 50 horsepower motor. It nearly killed the generator!
Or you just have 3 phase power at home (laughs in Germany).
aside from running carney rides, and maybe a shed with a gigantic cnc or end mill - what are the reasons for pushing 3p to the domicile level? I have no doubt there must be, DE knows engineering so…

nods knowingly
Indeed. 3p.

Where I’m from that’s enough for your ice lollies, your entry into the picture house, with enough left over for the bus home!
How many belt onions?
Wasn’t the style at the time.
I mean if you’re going tonreplace the motor just put in a small car or motorbike engine at that point.
Shut up, nerd! Let me have my gravitron
Yeah four-eyes! We want results, not complaints! Now get back in the HOLE!
Nothing that a couple of cat batteries hooked up in parallel can’t fix.
Sounds like an innovative, potentially disruptive technology.

I mean a residential area home isn’t gonna have room anywhere for the thing in the first place.
which is why I had mine installed out back behind the stables, that we me and the livestock can all enjoy it.
Mmmmmmmm, Milkshakes…
His milkshakes brings all the boys to the yard.
And they’re like, it’s gravitron.
Damn right, it’s gravitron.
I could teach you, but it’s five tickets to get on.
You’d also need a buddy to be the operator for it to work
Nah, just get a Bluetooth power button that you strap to your wrist.
Power company asked if I wanted a three phase meter when I was checking power requirements for wiring my shop up.
I just needed a different meter.

Ooooh. I could hook this up outside my uncle’s store.
I hear him talking about his setup all the time when something goes wrong and I regularly hear “it’s 3 phase”.
Good thing my house backs up to a funfair! Place in garden, unplug the nearest fair ride… et voilà! New income stream for me!
Three phase motors are the bane of every siren enthusiasts’ existence for this reason. Anything with a motor over 5 hp is likely three phase.
Nowadays VFDs have gotten cheap enough that you can just use one of them to create 3 phases.
Or you just have 3 phase power at home (laughs in Germany).
(I actually dont right now, but my house is one of the last ones not to, and its all already prepared for it)

jesus I saw people in the 2023 vid w/o hearing protection - like… neat event, but do you have minimal hearing protection at all?
you can’t control idiots but… perhaps… you could make them stand at a safe distance?
not personal criticism just damn… got my hearing loss in the army, it’s not fun.
Some of them seem to think they’re immune to hearing damage, which bewilders me. Smart enthusiasts have proper hearing protection.

Usually, there is a 3 phase outlet in the kitchen for electric stoves
ty.
It reduces the thickness of the cables and improves the balance of loads over all 3 phases.
Could be done with a large enough rotary phase converter assuming the electronics can tolerate the funky power
The problem would be feeding it enough power
Could get a large dedicated panel and rotary converter.
