When shopping for AC servos on ebay, i was very confused at the number of options, and mysterious part numbers.
I made a guide to help sort though the listings, and decipher the part numbers.
Here it is.
General AC Servo notes:
- Pretty much any series is good for hobby work, usually with motors sized between 100 - 750W
- 11 bit = 2500ppr, In my opinion, the coarsest resolution suitable for servo use
- More resolution is better
- If in doubt, check the servo drive manual. They list compatible motors in there also.
Delta ASD series:
A Discontinued, assuming 11bit
A2 standard 20bit, manual also shows 17 bit, 11 bit, and Absolute encoder options.
AB 11 bit encoder
B 11 bit encoder
B2 17 bit standard, 13 bit magnetic optional.
Notes:
- All models have at least analog speed/torque input and position input.
- Single phase input up to 1.5KW

JE 17 bit Compatible motors HF-KN/SN
JN 17 bit Compatible motors HF-KN (400W Max)
Notes:
- Some motor types may be irrelevant for hobby use, not compatible with single phase drive.
- All have analog speed/torque and position input
- Single phase input up to 750W
- Have seen J3 drive sold with HF-KP motor on ebay

panasonic a5II 20 bit
yaskawa SGDV 13/17/20 bit
yaskawa SJDE
Anyone care to add or clarify?
I haven't done much research on the panasonics or yaskawa.
I think the yaskawas and omron are almost identical, a lot of info may transfer over.
