    Where to get a drive sprocket to fit an eTek/Mars

    Here is another way to go.ON line is a source called electricmotorsport.com . They list the front sprocket you are looking for and they make custom rear sprockets that have the bolt pattern for whatever motorcycle you say. Plus you can order it for a #40 chain so you can make an all...

    DUSTY ARCHIVES

    I was looking at the you tube video def 215 posted (we are traveling the same road). After it had played out one of the related videos was for an axial flux motor with serpentine coils.I said "Hey I have seen this configuration before." I really think that some of the minds that feed around...

    axial flux motor?

    Nice job. I am trying to get where you guys are at. I have most of Axel Borg's books on building your own electric motors . I also have some books on homemade wind generators that I should be able to trick into thinking they are motors. Again nice job.

    Where to get a drive sprocket to fit an eTek/Mars

    I bought mine from BARSTOW INDUSTRIAL a hardware store here in Barstow, California. I don't remember having to do any work on it to fit it up.I also bought an 'A"plate sprocket that also was for a #40 chain that I had to change the 3/4 inch hole to about 2inch which I did by drilling a bunch of...

    AC motor on DC?

    thought I would jump in here.We plug drill motors into the 74VDC receptacles on the locomotives at work .They have a little less torque but we can apply a hole where we need it. Remember a universal motor is basically a series DC motor.So if you hit with 120vdc with no load on the shaft it will...

    SoCal Motor Bicycle Race Sat Oct 22nd 2011 Grange Race Track

    Just wanted to say what a nice experience it was to see what can be done with tomorrows technology.Most of the gas bikes were beautiful machines but the difference between gas and electric is like the difference between flying and levitating.I enjoyed going back to the railroad yard and telling...

    DIY electric motors

    Hi Axel ! I bought your books 500w DIY brushless electric motor, and Build your own Electric motor. I was hoping you could share with me some of the technical sources that helped you get the knowledge of axial flux machines that you have. Great accomplishment!

    The "Altermotor" (A Build Thread)

    Thanks for the feedback Modern. I just wanted to post this as close to the Consequent pole post as possible. That is when you energize the staor winding for the magnetic probe test.You will be using either several D cells,a lantern battery, or a car battery with a tail light in series with it to...

    The "Altermotor" (A Build Thread)

    Hi modern. I think what you have is a consequent pole connection. The math works for this pattern. I hope I am reading your discription right. 12 claws .Is that 6 from one end and 6 from the other. Then it is a 12pole alternator. Here is the neat part.You can check with your magnetic probe.Draw...

    The "Altermotor" (A Build Thread)

    I ASK THE FRIEND AT WORK WHO DOES ALTERNATOR REPAIR ON THE SIDE WHAT HE USED TO CLEAN THE STATOR.AND HE TOLD ME "SHOUT" AND HOT WATER. THEN DRYS IT IN THE OVEN ON LOW FOR FOUR HOURS. I HAVE STEAM CLEANED SOME STATORS AT WORK THEN DRIED THEM. GOOD LUCK HAVE FUN BE SAFE

    Alternator Motor - Thee itch I need to scratch

    Thanks for the info now I have a choice to make . I CAN REVERSE THE ROTATION EITHER BY SWAPPING TWO OF THE PHASE WIRES GOING TO THE MOTOR OR RE PROGRAMMING THE ESC AND THE WAY IT GETS WARM DRING PROGRAMMING EVEN WITH A LOW CURRENT SOURCE IS SCARY BUT IT IS THE RIGHT THING TO DO I THINK MAYBE...

    Alternator Motor - Thee itch I need to scratch

    HI HAROLD IN CR. I HAVE BEEN DOING SOME RESEARCH AND I THINK YOU WERE RIGHT ABOUT THE ROTATION MIGHT BE WRONG THE ALTERNATOR IS A DELCO 10DN AND ACCORDING TO SOME OF THE SPECS I HAVE SEEN THE ROTATION SHOULD BE CW. DRAWING AIR IN FROM THE DIODE AND EXHAUSTING IT OUT THE PULLEY END.THANKS YOU...
