Thread: motor with ssg circuit not working help please

  1. #1

    motor with ssg circuit not working help please

    hello my name is andre and I am a very noob in electronics but i am busting at the seems to try it out for myself so please forgive any naivete on my part.

    i am trying to suply my house with this motor, the idea is running the motor that will run an alternator and the alternator will power the inverter.

    the whells are made of aluminium 45cm diameter, the magnets are 7,5cm 5cm 2cm, pull force 10,1 kg , the circuit i used 2n3055 transistor, and i tried to use 470ohm resistor with 1w, and also with 0,5w ,
    i also tried with mjl21194 transistor. the wire is AWG 20 and AWG 24 for trigger.

    any thoughts why the motor does not work?

    i made before one bedini motor with a bicycle wheel with ssg circuit one transistor and that one worked..

    any help would be very nice

    best regards

    hello PradeepKumar, i check everything is ok. i try different loads nothing works. i thing is not trigger the transistor how can i calculate the resistors that i had to use? i have to use an oscilloscope to tune? thanks for your replay.

    best regards

    Have you tried switching/swapping the trigger wires?
    take the trigger wire that is connected to the neg of the battery and put it on your POT and take the trigger wire that is connected to the POT and put it to the neg of the battery.

    hello Patrick,
    i tried to do what you said but it doesn't work... do you have any suggestions?
    best regards and thank for the replay

    Hi andre_kaetano,

    I don't see any common negative primary battery connection to the emitters in your photos. Where do you have the primary battery negative connected? It appears to be connected only to the trigger coil.

    Also, the magnets are oriented the wrong way on the wheel for best performance. The long dimension of the magnets should be across the width of the wheel. The narrower dimension is about the same as the diameter of the core, which is required for best switching and the longer dimension is about the same as the diameter of the coil windings. The way you have it, the magnet is over the core too long each pass, and the coil winding isn't exposed to all the available magnetic flux.

    Good eye Gary, emitter to primary neg.
    I see the other picture now regarding my question of the extra diode. It's actually from the transistor on the far right...
    Disregard my previous post and listen to Gary :-)

    Hi All,
    Which extra diode..? I guess its the base -emitter protection....!

    Use a continuity tester between collector and emitter while you fiddle with it. The kind with sound is best. It can tell you a lot.

    hello Gary Hammond,

    thank you so much you are the best i miss that Now I can hear the sound of the coil when I turn the variable resistance which is a good sign.
    but is not working...
    I think now it will be a problem with the resistances to fire the transistors? what do you think?
    And I will change the magnet as you said.

    thanks for all the replies kind regards to all

    Hi andre_kaetano,

    Try unhooking all but one power winding and one transistor to see if you can get it running. It's easier to work with only one circuit at a time. Then when you get it running on one, you can hook the rest of them up the same way.

    Also try reversing the trigger leads again. Try it both ways. It will only work one way, and is an easy thing to check out. I think Patrick already mentioned this to you.

    And turn the magnets long ways across the width of the wheel. You do have all the magnets with the same polarity facing out don't you? Either all north out or all south out?

    I'm sure you already know from the first one you built that these do not self start. The wheel must be spun fast enough by hand to get it triggering and running.

    You said in your first post ......
    i am trying to suply my house with this motor, the idea is running the motor that will run an alternator and the alternator will power the inverter.
    This is not a motor, but rather an energizer. It won't pull a conventional alternator or generator. But it will charge batteries that can be used to power inverters or dc loads.
