To All,
Does anyone know if there is something I can buy on Amazon to couple the two motors together fairly easily?
Thanks!!

I am going to film a couple of tests that address this issue with ground side.

I think if I am not mistaken that the my1016 is around 75% efficient and from my tests of stock motors I would say its even better then that.

In the Spring of 1999, Peter was nominated by the late Dr. Robert Adams of New Zealand for a Doctorate degree to the Board of Governors of the Open International University of Alternative Medicine in Colombo, Sri Lanka. After a 9 month review of past experience and published work, he was granted a Doctorate of Science degree (honorus causa) in Complimentary Medicine, based on his previous life work.
Lindemann is among those to whom I referred when I said this: "It is opinions of those who do not understand how motors actually work." I encourage you to seek the truth motors and generators.
BTW, I did attempt to engage him in a discussion concerning physics where we disagreed. He simply went away and then shortly retired from this forum. I welcome an opportunity to discuss his opinions of why, as you say, motors are inefficient and underpowered and how 85% of the current is thrown away.
Regards,
bi
ps. Sorry for off topic. Please drop it and return to testing.

I don't understand how a motor "throws 85% of its current away". You can see the current into the motor is equal to the current out of the motor, always.
"how inefficient and underpowered conventional motors are." This is BS. Yes, I've seen that several places on this forum. It is opinions of those who do not understand how motors actually work. Electric motors are extremely efficient and designed to meet the appropriate power requirements. But that is off topic.
Are you opposed to me duplicating your experiments even without the modded motor and posting resulting data? I thought you wanted folks to build and test.

Peter Lindemann, has PHD in motor/generator science. He has a lot of books and material and on the subject. I have built and designed several very efficient motors in line with the principles he outlines. I know first hand why and how they work. If you have problem with my opinion based on my experience then go argue with him.
Also if you feel the need to challenge everything said than do so based on the material at hand and replicate the project as outlined, or go away.
Thank you for your understanding for our need to move forward...

If it's on the pos side then your measuring both boost and motor current combined and your readings/time may be inaccurate. You might want to double check that...

Efficiency???
Bi,
When you speak of efficiency of a motor you are thinking of how much of the input energy is CONVERTED to mechanical energy, are you not?
When WE speak of the efficiency of a motor we think of how much of the input energy is or CAN BE returned without being used. Which is “MORE” efficient?

Unlike the motor your using which is conventional and throws 85% of its current away just charging the coils after the initial inrush and first rotation. This is pretty documented stuff in this community, especially how in efficient and underpowered conventional motors are.

@BI

The yellow clip is to hold the multi meter (I didn't mention that), The current is high because I am stepping up to near 36 volt. Thats modified motor which you have no experience with at 24 volt runs about 1.5 amp no load. The jumpy current is because the motor discharges back to source, a good portion of we put in it and the BEMF. Analogs jump around to.
A scope is the only probe that will average out the RMS value of the current and make it appear stable. The only thing that limits the current going into the motor is time on. Its in constant inrush state.

I have another longer type my1016 motor that I want to modify and use as a smaller generator.
Since the rotor is longer would I use the same method as the prime mover motor? Or different awg, number of turns, and method of winding on the rotor at 40,30,30 turns?
I like the videos. Was going to setup the same way but, my marine batteries are 115 amp hours. The test would be too long and the motor way too hot.

I would save the motor, give me a few days I am putting a small little gen together. If it works I can send you the pieces and a some shaft, probably bearings too. You'll have to get the wire though you'll need a 11lb spool for both coils. You already have the magnets.
The modified motor should be able to get the rotor up to speed enough to cause the acceleration.
Email me and let me know.

My results

Start.

Finish.

Sorry about the sound in the second one I had to move a box fan to help cool the motor and forgot to turn it off.
Its just video its not proof. You have to prove it to yourself.
Matt
I looked over your vids a bunch. I suspect the accuracy of the current reading. Really seems like a lot of power (~48W) to run the motor at no-load. Also, it looks like a yellow test lead clip on the battery negative terminal. Is that just to secure the test probes or does it connect somewhere? Wouldn't happen to have a good old analog ammeter to check that battery current?

Still kind of busy wrapping up some heating projects but I find myself pondering and building small circuits in the late evenings similar to what you and Dave are doing. Keep up the inspirational works !
