Thermite, Yes I looked for the graph in the manual and didnt find it. I know they are included in manual with some machines. My mazak lathe has one that shows exactly what torque is available throughout the rpm range. I will make some notes for sure, thanks again
The world seems to have gone through a phase from where the curves were published as part of enabling design choices, then sort of pulled-back behind the fences - even "NDA" - as product was more closely integrated into a system or function and the "integrator" chose to apply the motating goods in ways of their own and USE some of those "special" configurations.
Time was, one took a paper feeder on a copier or a can or bottle feeder on a vending machine apart, found a Bodine motor, that motor was what it was, and Bodine published ALL the specs, curves included, whomever had bought their motors.
Current era, you MAY - or may NOT - be able to find "white papers" further back up the chain among the OEM motor or servo maker's pubs. Even if you DO, the drive system and controls it is powered by and answers to may have a great deal more to do with what happens at the tool-tip than the raw nameplate, one application to another.
The final-assemblers have gotten THEIR Engineers into the act and engaged in altering how they motivate the motators as it is all a competitive business and each player seeks an edge - or several - at the most favourable cross of performance, cost, and service life - even physical size and shape.
The "good news", of course, is that after a time, it became fair-obvious whose machines were good at what tasking, were durable or not, economical to run, or less-so, and we could - and still can - mostly just go off and put them to
work.
