I have been a member before but never posted and my account was deleted so I figured I better say hello. I am a new lurker here to gather information and ideas to build a racing rig. They rig I would like to build is a 3DOF platform style using 3 phase AC motors with VFD's but this might prove to be a little pricey. I would also consider DC motors with the 3DOF platform if they could be powerful enough. My fall back is the classic 2DOF seat mover but moving pedals and wheel too.
My biggest issue is sourcing proper motors, particularly on the AC side. What general specifications should I follow?
Thanks,
