John, Assuming this is a rack & pinion type configuration:
angular v (w) = linear vel * pulley radius (R) angular accel (alpha) = linear accel * R Jreflected = (gantry mass + motor mass) * R^2 inertia total (Jt) = Jmotor + Jreflected Torque reflected (Trl) = (Ffriction * R)/efficiency (n) Torque peak(Tp) = Trl + ((Jt*alpha)/n) P = Tp*w 2015-09-09 14:12 GMT-04:00 John Thornton <[email protected]>: > Thanks for all the info, now to chew on this a bit. > > JT > > On 9/9/2015 5:53 AM, John Thornton wrote: > > I need to calculate the power needed to move a gantry.
