Full size motion platform motors

hi, could anyone recommend the best type of motors to use for a 6dof motion platform?

I am using boat winches, noisy but I wanted something that I knew could carry the load. That is the cheapest option that I know of. There are others who designed theirs around large AC motors with gearboxes. Have a browse through the forums, Speedy did his 3DoF with AC motors but could easily be adapted to 6DoF, MerchanE did his with wiper motors but that is a seat mover not a full platform.

@vulbas is doing, and about completed, a 6 dof using ac motor/gearheads/vfds -
I am also about finished with a 3dof ac setup - the AC route with VFD's is an expensive endeavor - but as I did, found all mine on eBay and they were all NEW - about 1000.00 us - vs. full price of 3400.00 us.

Good luck and please post you progress. We love new members and new projects.

It somewhat depends on what the main purpose of you're rig will be used for, flight or racing, and how much total weight it will have to carry. I would have to say DC motors though because they will work in either situation! And with 6 of them working together, you should be able to find some with enough power to avoid the usually more costly AC route. For racing though, DC for sure!

Hi I found 750w servo motors for $ 150.00. I do not have experience in building YES, but I think this servo motor is a good option.

Please inform if it is a good application for simulator 2 dof

If I'm reading "right", the maximum output in ft.lbs. = 10 - Not enough torque to move very much.
I'm using AC motors 1hp/60:1 Gearheads and my output in 113 ft. lbs., quite a difference.
Some of the heavies here may be more informative, but I would never use a servo or motor/gearhead that would only put out 10 ft.lbs. torque.

Thanks
