Heya guys,

Right now I’m planning on building a large “science factual” spaceship with a rotating centrifugal-gravity hab-ring.

Design Drawing

I was wondering if anyone could give me some hints/suggestions/how-to for powering the rotating section. The Hab-Ring is going to be made with click hinges into an octagon - obviously it is going to be studs-in (mostly). I want to have removable panels along the walls of the HabRing so people can see the interiors

The counter weight ring needs to turn in the opposite direction as the main Hab-Ring. The whole thing will stand on a large base of some sort.

Questions:

Will I be able to run both rings off of the same motor? Will the motor be strong enough?

If the single motor isn’t strong enough to run a single ring, can I use two motors in tandem? How?

Anyways, thanks in advance for the help!

-Lenny

Yes you can - you can connect as many motors you like in parallel. Their output shafts can be connected (...) (20 years ago, 24-Nov-04, to lugnet.build, lugnet.technic, lugnet.space, FTX)

(...) Hey Lenny, I just wanted to pipe in with my two cents. I've been working on a ship with a rotating mid-section, though it's probably not as large as yours is looking, it's a medium minifig scale ship, and it only has one rotating section, in (...)
