    its insane....

    Well after a full three hours of winding and an arvo of soldering it is running. Its a BEAST! Theres a little rattle from one of the bearings, it isnt seated tightly, Im not sure if I can fix it, otherwise I am totally happy with the outcome.

    At the moment I have it running off the full sequential bipolar switch which works really well. I have an external Cemf load as another battery that is slowly charging up. I have to make a commutator now for some other experiments, and I might also try an SSG circuit, but I will make it non permanent so I can switch between both. Ill just be doing that for fun, this bipolar circuit works a treat

    Oh.....by the way.... its septfilar (7) and I only have one power winding hooked up at the moment. Each power winding I add to the original circuit increases speed and torque. I am not sure if it is beneficial yet for each power winding to have its own bipolar circuit or if it makes no difference if they are all parallel joined at the one circuit

    I cant stop the shaft with my hands on 24 volt, and the circuit is good for 50 or more.

    You have to build this thing guys, it rocks! Im posting a couple of vids on the tube now.

      first vid here

      Oh and I take back what I said before about not being able to stop it on 24 volts.

      I CANT STOP IT ON 12! I can slow it down, but as it slows down it draws more amps and it gets harder and harder to stop!

        Good work ren, how much amp draw?

        Apparentely with this motor type attaching a generator can be cop > 1.
        Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

          thanks Patmac.

          Amp draw is totally adjustable from under 100ma to whatever you wish. On the video it was running at about 500ma. One of the resistors in the circuit can be replaced with a pot and this controls amperage quite effectively.

          I reckon its Cop over 1 already.....

            Nice work, ren
            I got my huge 1"x1"x4" neo magnets, they are so strong that I can't get them separated even with thick spacers between them. This will be a chalane mounting them on an iron core, I am a bit scared
            It's better to wear off by working than to rust by doing nothing.

              lol Jet, nice!

              You might have to build a little jig (non magnetic of course) to slide them apart, you'll never get them apart by pulling Id suggest making a clamping device to hold your rotor too, one that isolates all the other poles so it cant spin on you while you set them. The little aluminum angles that I used on mine worked a treat, though they probably wouldnt be strong enough for Neos.

              Whatever you do be careful champ.

              I will be posting some more vids soon, and doing some load (mechanical) tests. And if anyone is interested I might put a little tutorial/project overview together for others that may be interested in replicating.

                Of course we would be interested (at least I certainly would)
                Keep up the great work!

                    Done gentlemen. Tute on its way.

                        Yes be careful. I use leather gloves to work with them Fun and dangerous all the the same time. You going to make a window motor as well?

                          Yes, Mart.
                          I am also going to build a window motor, but instead I will use strong neo magnets. This will make the motor slower but give it greater torque. I already have six 1"x1"x4" neo magnets that are magnetized through thickness. All I have to do now is make some cad drawings and send them to my machinist. There is SO much I have to do and so little time...

                            Im amazed you fit in all you do JET?

                            Incase you missed it Jet there is an awesome post on the advanced forums from Carl Hurst on the window motor, its worth a read. The Neos will provide great torque, Im looking forward to seeing it run!
