DonInReno Posted October 2, 2018 Report Posted October 2, 2018 I’m kind of excited about this servo - is it just me or does it appear to have a squarish body as if it or a variant using the same form factor is perhaps NEMA sized to directly bolt up to a geared reducer? Quote
Members dikman Posted October 3, 2018 Members Report Posted October 3, 2018 Don, if you're referring to the one R8R pictured it appears to be pretty much identical in construction to my servos (in other words, fairly "standard" construction).

DonInReno Posted October 3, 2018 Report Posted October 3, 2018 (edited) I’d love it if there’s enough room on the front cover to match a NEMA 27 or 34 hole pattern. The distance between the mounting holes is....wait for it.....2.7” or 3.4”! Lol this looks like a nema 27 bracket and the other is a planetary reducer that fits a NEMA size servo motor Edited October 3, 2018 by DonInReno Quote

Lol Looks to be about 76mm (ish) spacing on the end plate mounting holes, with another set of holes inside those at 40mm to mount the belt cover bracket. Quote
Members dikman Posted October 3, 2018 Members Report Posted October 3, 2018 Interesting. I just checked mine, I have two types, a 550w and a 750w, same brand (Lishui). The 750w is 68mm and has a round front, the 550w is 70mm and has a square front like that planetary gearbox. Quote Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500.

Members dikman Posted October 3, 2018 Members Report Posted October 3, 2018 I've still been searching both aliexpress and alibaba trying to find a match to that unit R8R has posted, but with no luck. I can't find any servos rated at 1100w, the closest is 800w, this model is a close match at 800w and the control panel appears to have the same functions (LT-800W, made by Lishui). There also don't appear to be too many that start at 100 rpm, all the ones I've looked at start at 500 rpm. Curious.

The controller is different though I think, and that is where the magic happens. The one from Keystone is $75 cheaper too. Edited October 14, 2018 by R8R Formatting Quote
