    But then your motors will have no holding power with such a low ratio.I thought ac motors would have a advantage over dc motors in that they have more holding strength (torque),they also take up more space :thinkBeginning to think I should just stick to DC motors,at least my AC motor dream :(didn't cost me much,6 ac motors and three vfd's just under 120 dollars so far.Guess ill just do some further tests and see if its worth it.Thanks for the help guys:thumbs

    Another option would be to use 2700rpm engines and use a 1:50 reducer, it should have more retention force, it also depends on how this platform is designed to affect the retention more or less
