    I finished the housing for my speed reducer so that the input shaft is
    exactly at the same height as the motor axis. I attached the speed
    reducer to the motor and did a test run. The reducer gear ratio is 15x,
    that means it reduces the speed 15 times and increases the output torque
    at the same ratio. The input speed is rated 1750RPM, I was putting in
    about 2500RPM. I will have to change the speed reducer oil. The speed
    reducer output was about 170RPM. If my permanent magnet alternator puts
    out 12v already at 150RPM, then 170 RPM should produce about 13-14V.
    Will see soon how much load the generator can hold. Here is a video:

    thats really neat! can you tell me the model number of the permanent magnet alternator your going to use so i can research it for my next motor?

    RE: faster than drained.

    Hi grizli..

    1. You have the energy comming out to charge battery #2 charing battery. This is not the place to look to get 100% back. You typically get only like %70 recovered energy here.

    2. Hook a generator to the motor, and yes, I am told that there have been machines that make up the other 30% consumed by the batery so you exceed the amount of energy. I have not seen this, but I am led to believe the possibility is real with the testing I have done. The generator combined with the recovered energy going to second battery is why everyone is attempting to replicate this.

    Much of this has been covered earlier in the thread, and building your own unit helps to understand the whole concept.

    I know my converted motor has shown me a good part of what is involved. Now to refine it, you would need a machine shop to see what Jetijs is doing.

    the significant difference between our motor and a transformer is that the "extra energy" is "mechanical" and needs to be measured accordingly I.E. a dyno test then "compared" with the "reduced input"(input-recycled BEMF) we pay for electrically. a regular coil on a core transformer has no moving parts to take advantage of this "mechanical" benefit... i went through this line of thought myself awhile ago. hehehe

    hope this helps!!

    but that gave some interesting ideas for my 2 pole motor. i am now building the circut so each pole is totally isolated from each other. each pole starts with its own 24v battery pack, has its own transistor circuit, and now i am working on using a duel optoisolator so i can use 1 reed switch to control both circuits. then
    maybe i can dump the BEMF of 1 pole onto the primary side of the other pole!
    Yeah let me know what you find out there, that idea has been going aronud ni my mind a lot. dump one coil to power the other coil, and if you can figure out haw to make it go back and forth then you only need to add enough energy to cover the losses. an idea I had was to back teh coil with bifilar windings but have one wire of the two go longer and keep winding it so you have two wires like a bifilar winding but one is much longer and adds more turns to the coil. then collect the collapse of the longer wire which wolud have more voltage and then dump that into the other coil for power, so it becomes somewhat like a tranformer combined with a motor. the collapse have higher voltage than the drive pulse that way. Only thing I have a problem with is the timing. the collapse may happen so fast that it wolud not be at the right time to hit the other coil so maybe store it in a capacitor then then dump it when needed. Just some thoughts anyway.

    Dear Grizli,

    Actually, no one is saying that there is excess energy in an inductive collapse. If you would have read the whole thread you would know this. What we ARE SAYING here is if you make a motor with an iron rotor and an inductor as a stator, and then attract that rotor into alignment during the time you are charging and discharging your inductor, then the COMBINED energy of the system can be COP>1. In a constant inductance system, the amount of electrical energy that is recoverable is on the order of 95%. In a variable inductance system, like our motors, the amount of electrical energy that is recoverable is on the order of about 70%. So, if the motor section can produce mechanical energy at a rate exceeding 31%, the conditions for COP>1 are met.

    If you are interested in posting here, please read the thread from start to finish.

    Thanks,

    Peter

    ...

    So WHY using motor if we can the same effect on TRANSFORMER !!! Question is HOW

    Nice drawing.

    I see why you could not have a return stroke on that setup becaues you iron rods the full length. I was thinking to have a stainless steel shaft and then have a larger diameter iron cylinder/piston mounted on it, that way it can go past the coil in both directions.

    motor laminations

    Where is a good source for getting motor laminations custom cut to your specs and a reasonable price. I am working on the attraction motor and a linear alternator to use with a thermoacoustic engine. I need to get some laminations cut and don't have a clue as to where to look. I don't think I will be able to canibalize any microwave tranformers for this project. Any help is greatly apprectiated in advance.

    Sincerely,

    George

    I see what you're saying for a return stroke in solenoid style.

    I drew this up quite a while back:
