Hi, been reading all the stuff comming across on big servo motors, here is my go at it, take a typical Getty's servo motor, or a Peerless Porter servo motor. BIG, heavy but very powerfull...current levels high enough to weld steel with. you have in your hand a servo drive that weights 6 or 8 oz's is not gonna do it.
add 500 or 1,000 lbs of table and the drive needs to handle 150 to 350 amps
capacity for seconds at a time. the last 2 Gettys servo boxes i junked weighed 145 lbs and had (3) 300 amp SCR's to control the motor with.
I do think the electronics inside the late model servo drives have good stuff, but time for someone to design a servo drive with say 100 amps of real power handling, would make these motors very usefull again. IMHO cul brian f.
