Hi birdhouse.
I have the HF clamp on digi meter. It measures AC amps only. As the guys said just clamp around one wire at a time. It works prety fair and will get you in the ball park.
Its true I've never built a furling wind generator. One reason is I've never flown a machine larger then 7 ft.
I'll be building some 8 to 12 ft machines in the next coming year and they will have furling.
When you and I opened wiring acces area on your Fanuc as you recall the star point was there and very accesable.
If you wire this unit JR you'll get more rpm and power from your drill bench test.
This should remove some of the stall on your drill and gain you abit more amperage.
I should recive the 2 Fanuc motors from my son next week. I'll do many tests and report my findings.
I hope mine comes with the shaft adaptor shown in the net pictures. If not I'll have my son machine the nessesary adaptor.
I have a 100 Lb. 180 volt dc motor that should drive the Fanuc into some decent power. If not I'll add a second 100 Lb. 180 volt motor. We'll find out what this baby can do.
I'll keep an eye on its thermal condition with an inferred thermometer.
I will need some guidence for blades as well. I think a good assortment of test info should be suficiant for the blade GURUs here to make a sugjestion.
Keep us posted on your progress.
