Here's a video look in the extra information text part for the numbers this isn't the vid I was looking for .but it will do .

The thing is that there all using small toroidal cores and it doesn't seem to be recycling the back emf for a 80% energy return there just throwing it away . so I'm going to try the pipe notion for more power .I like the idea of motor being on 1% of the time and creating power 100% of the time .and the input discontent from the out put .

A relatively simple method for measuring the mechanical output is shown in the first 13 minutes of this video:  https://www.youtube.com/watch?v=OSJF3GlYGVc

Thanks for posting that. I haven't seen that video in many years. I was really hoping to find a copy somewhere that the voice lines up still but I haven't found one. I had forgotten about his explanation in the beginning. That is such a great resource video I had forgotten about. When I saw it long ago, it was the first time I had ever really understood back emf.
