  • @turtlezed Dis a guys project. Not cool at all.

  • What an interesting idea & video. Thank you for posting your hard work. Incredible.

  • man....i should play this when i lay down in my bed.....im sure i'd be asleep after a minute...or two....yawn....he reminds me of an old college tutor i had...he had a monotone drawl and used to send me to sleep, absolutely nuthin i could do about it...he he...

  • I like the video. I'm just starting to learn about electronics and tinkerwith things. I saw this and loved it ,now I want to try to make one. can I run this wthout the computer ?

  • Dont' forget to include a "two-phase on" intermediate step, especially at low speeds. Most machine tools mid 80s to mid 90s used digitally controlled steppers... "cogging" has to occur at some speed/load combo... now it's series or pm motors usually pulse-dc controlled - smoother and precise enough when used with lots of position feedback. Enjoyed the vid!

  • un saludo  daveti esta muy interesante su trabajo un saludos

  • how would this work with those permanent mag alternators sold for windmills.

    this is amazing.. direct drive car wheels..

  • how would this work with those permanent mag alternators sold for windmills.

  • Nice presentation!

    A high voltage with a swamping resistor in series with steping coils makes a more constant current and more snap but wastes a lot of energy so may not be wanted.

    .

    I think you will find to change your software to percentage ( of the period) pulse width to accomodate easier software "playing" That way only one input figure will need to be adjusted to ramp speeds up and down. You will find the pulse width will also lower noise factor generated by "tuning"

    Best of luck!

  • Dave there are a few e bike enthusiast that would like an inexpensive way to use an alternator as a bike motor. The quest I guess is to get the optimal torque on take off or start up and the optimal rpm to reach a good city speed 20 to 30 mph with out having to use jack shafts and belt drives and do it with motor controllers. Right now off the shelves models like i-zip e-zip run between 375.00 to 1000.00 preform about 18 mph for about 15 miles then its a 6 to 8 hour charge to take off again.
