have you given any thought to using hydraulic drive.
closed or open loop system very simple systems and braking not a problem if you need further info let me know.

hi there about your centrifuge braking why dont you use a hydraulic drive very simple and no problem braking to come down to plough speed +-70rpm works like a dream i have done two latest one using load sensing with speed feed back
for spot on speed control at start ramp to charge speed ramp to...
hi there
eulers formula can be adapted for cylinders,
Fcr = pi2 x E X I/L2 ----- (eULERS )
sub. pi x d4/64 for I ( solid round shaft )
and 2.07 x 10*5 foe E (steel )
Fcr = pi*3 x d*4 x 2.07 x 10*5/l*2 x 64
then Fcr = d*4 x 10*5/l*2
then d*4 = Fcr x l*2/1 x 10*5
d = 4th root of Fcr x l*2/1 x...
hi there regarding your cylinder synchronizing.
i have used gear dividers and valve dividers, cylinders will stay in to about 15% of perfect synchronization.
in designing systems the cylinders should bottom out against a positive stop in both directions, this i have found helps greatly, also...
hi there, a few tips hopefully they will be of help.
New system.
1. pump loss 15% of input power.
2. motor loss 15% of input power.
3. R/V loss BTU/HR average ( 1.5 x PSI x GPM )
4. Flow control loss use press diff across in to out as PSI in calculation.
5. Press reducing loss if any use same...
