Re: Lower draw under load DC motor video

Hi all
 Here is another video from over a year ago, again filmed from my computer screen so youtube will take it... this the" rotating invertor", with variable speed control running a small AC rotovertor motor...sorry about the noisy motor, this my first attempt at this actually was pretty successful overall and could be much better next try, speed limited by solid state relays I think...

Hi all
 Here is youtube video link that I just filmed off my computer screen  as it had some strange format to it and youtube would not accept it straight from computer...this video has been sitting in my laptop for over a year is pretty good and is of my motor design where you have 4 NS rotor magnets fairly close together as shown, and each side of this rotor are 4 coils with blacksand cores that stretch across between two rotor magnes, and are wired to both pull and push at once all 4 rotor magnets at once. Polarity must shift each pulse, so really this is an AC motor but I call it a an alternating DC motor....Anyways this was experiment using boost convertor feeding the H switch with the solid state relays. The relays are pretty slow probably would be much better with mosfets and no solid sate relays but it works OK very interesting how draw goes down, voltage going into motor  goes up..
