I'm still trying to choose a motor I think would be appropriate... During my searching I've found mention that geared motors can sustain weight while not powered or something, which is appealing, but mostly I was looking at reversible DC motors since I read that reversing the polarity of a regular motor can damage it?

What's your opinion on this? And should that circuit still work with a reversible motor?

That circuit will only work with a reversible DC motor. I'm assuming you will by using something like a small model type geared motor. You would definitely need a geared motor so you have enough torque. Geared motors keep their position simply through friction in the gear box, especially worm gear motors.

You should fill in your location and then someone may be able to point out a suitable motor in your vicinity.

Ahh! Thanks for that info!

You might be able to help me out, I'm actually from Sydney... Any suggestions?

The top on my list at the moment is probably the MOT-203

DC Motors

What do you think?

If you wound cotton around the shaft it would wind in at 6*PI*160=3 meters per minute. So it would move your 1M in 20 seconds. At a radius of 3mm it will pull with a force of 50/0.3 = 166kg. The 202 may be a better choice, at 36RPM you would be able to use a small drum.

Okay, I'll invest in the 202 and do my best to set this up ASAP! I'm looking forward to setting this rig up... Thanks a lot for your help!

I'll be sure to keep you updated on progress and let you know if I come accross any snags!
