will fanuc 20s motors work with current model drivers

[js412000]

I bought some new, unused, fanuc 20s red cap axis servo motors at an auction . (this model is not made anymore)

The date on the tag is 96.06.

Were these made in 2006 or 1996?

Will these work with the current model fanuc alpha or beta servo drivers?

I would hate to spend money on obsolete servo drivers for a new machine build.

Probabally 1996 if they do not have the Alpha symbol on them.
With a very few exceptions, all the Fanuc motors are 3 phase 8 pole, the biggest variation comes in the encoder.

(Thanks for the plug, Sam!)

Right. I have tested my servo drive with a couple Fanuc motors in the A06B-0315 series with pulse coders. I am sending out boards for fabrication for the commutation converter to adapt these motor's signals for use with any industry compatible brushless drive. It takes both the B1..B8 commutation signals and the ABZ encoder signals, and produces standard UVW "Hall" signals.

This converter board is not on my web pages yet, but I should have it available in a couple weeks.

That huge motor runs REALLY nice with my servo amp and EMC2.
