Re: Motor Torque Question

BEWARE of the van-door motor.. we ran the numbers last year, and figured that it would have the torque to move our HUGE arm.. but we did not know that there is an over-riding clutch built into the motor.. the motor may put out X torque, but when you try to keep your arm stationary, you better not put much torque on there...anyone at VCU last year can remember the flying arm.. it was not pretty- the clutch slipped and intertia took over.. also beware of the FP motors- those gear boxes aint the strongest.. we attempted to use them to do a (i think it was supposed to be a 4WD/ car steering) skid steer and the plastic gears stripped themselves out pretty quick.. the FP motors will probably do fine as long as you do not change directions quickly or have the arm move due to gravity at all..
