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

Most probably - assuming the rings are both balanced all you need to overcome is friction. And they won’t be spinning all that fast.

I just figured how to do the different directions on a single motor (forgive the MSPaint drawing).

And speed is actually something I don’t want - the HabRing has to be very slow since I’m going to have detail I want people to see inside of it.

I’ve been talking with Soren Roberts on IM and have been getting some good feadback and ideas - I’m feeling a lot more confident about doing this, as this will be my first technic/motorized project. i have a deep fear of getting it built, turning it on and watching it fall into pieces.

thanks for the reply!!

(...) Cool! But don't knock yourself out trying to get it to run off a single motor - unless you only have one!! You'd probably find on the real craft, they would be driven independently, with computer synchronisation. (...) LOL don't worry it (...)

(...) The key thing is keep the center of gravity of the ring at the drive axle. If it is 1mm off then you will need a lot more torque, and the rotation speed will be non-uniform. (...) You can just use 3 bevel gears or this piece (URL) to do (...) (20 years ago, 24-Nov-04, to lugnet.build, lugnet.technic, lugnet.space)

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)
