I would like to run the numbers and see how efficient it is.
George, see the posts above for some of that data.
I have ordered an rpm meter but it didn't arrive yet, so no rpm data for now.
I'll measure the rpm when it arrives.
For the other data you need see this thread:
Here is some relevant data from the first post:
The original configuration of this motor was a 12 pole stator with 16 magnets wound with 2 strands of 37 gauge with 17 turns (ABC wye)
What software are you using to compute the efficiency ?
