Any chance we can get more info on separating the windings to go Star or IRP? I noticed a connection or two when I had my Fanuc motor open (wired Delta) and was wondering if separating the windings was possible, it would require cutting some lacing and soldering on some leads. Cutting the lacing would be easy, not sure if I could re-secure the lacing though, soldering new leads would be easy out on a bench, trying to work inside the motor seems tricky and I'm afraid I'd dribble hot solder everywhere and screw it up

All the yaskawas are wired star, three coil leads from one phase went to each pin of the Amphenol. I found a junction on top of the rear of the stator that had the 9 leads for the other ends of the coils.
Did you check if the wire connections to the pin had a single conductor, or multiple coil wires with a sleeve? Being wired delta, assuming parallel coils, it would be easiest to just run the wires to the pins. Each pin (three coils per phase) would have 6 wires, example on the U pin, one + set for U-V coils and one - set for W-U coils. And the same for the V and W pin.
I think Fanuc supported different voltages, that would be another good reason to run all the wires out to the connector.
If not, then you should have three junctions on top of the stator with the single wire to the connector pin.
I don't know if you should solder, or use a crimp pin to join the wires after getting the coating off the end. That's a lot of fun, I ended up sanding little itty bitty wire ends in my fingers to get it off. I soldered single-conductor extension wires with teflon coating on one set, the opposite set was already long enough, just added teflon sleeves to it. Then drilled holes in the plate separating the stator from the encoder end, and moved all the connections into the encoder box. No brakes to mess with on these yaskawas, if you can get servos off a process or feeding machine, then you can avoid the brakes that are on the robot servos.
