    5 Lines of Code to spin BLDC?!? On Youtube.

    Hello All, The link below is a Youtube video by Linas K, where he demonstrates '5 Lines of Code' to spin a BLDC motor. :shock: All he basically needed was an STM32 and an encoder. Would appreciate any ideas or info on a complete sample code+lookup table. If it is really that simple, it would...

    A123 acquires IP and scientists from Leyden Energy

    So you get my point that big pharma HMOs, big oil, big brother, big banks, and corrupt court systems are the enemy - all stifle much needed innovation from prospering - but you missed the crux of the matter by saying that innovators need not bother seeking ownership or credit for their...

    A123 acquires IP and scientists from Leyden Energy

    Luke, There 2 essential aspects of patents (although abused by repressive rich and corrupt courts) is to first, not stifle inventive folk. Why waste your energy creating something new if there is no benefit in doing so (i.e. anyone can copy your work without consequences)? Second your are...

    2014 Formula 1 Hybrid Electric Motors!

    I agree totally with your point regarding Ferrari. Excuses doesn't win races. Proof: their hybrid La Ferrari does not support 'electric only' mode (unlike the McLaren P1 or the Porsche 918) and just uses the batteries to enhance its 12 cylinder engines performance. Its Ferrari in denial about...

    2014 Formula 1 Hybrid Electric Motors!

    According to a Shell engineer working with Ferrari the turbos spin a aroung 125,000 rpm in this video: http://m.youtube.com/watch?v=U-0_Fvlhdpk Mercedes' electric layout is beating both Ferrari and RedBull. The assumed ceramic bearings in these electric motors are incredible. Perhaps they are...

    That's the speed of the six cylinder gas engine. Not the turbo fans connected to the electric motor H which spins much much faster. You are very welcome!

    low inductance output stage contruction

    No offense intended All, because I sincerely do believe as Luke does that Lebowski's low inductance powerstage is a huge breakthrough and would like to find out from any capable ES experts with time on their hands how much they would charge to build it according to Lebowski's specs. PM me please...

    low inductance output stage contruction

    This thread seems to have died despite its revolutionary potential as Luke pointed out above. Is Hotrod's / Njays suggestion about the caps significantly better or more correct leading to less interest in this? No responses to my previous query too.

    low inductance output stage contruction

    Assuming that I have a very large stator that has 16 poles by 18 teeth, which would have ordinarily be wound with copper in this sequence - AaABbBCcCAaABbBCcC , how would I wire my stator instead ( as suggested in the above quote) to take advantage of Lebowski's low inductance output stage...

    Continue EV project or not? Need feedback

    Flathill is quite right. I can say right now that Figures 14 and 18 will be quite troublesome. This paper discloses nearly all patentable aspects. Where and how did you come by the link? It is quite an exciting read! Copying it again below for others. Thanks for it flathill...

    Continue EV project or not? Need feedback

    Luke - on their website they are showing a 'capacitive machine' that they claim is an ' electrostatic motor as a full replacement for motors and generators'. Presumably using the same method.

    400 watts in suitcase - can it power a Collosus or bigger?

    Thanks Dave! Actually I love the lack of noise in an EV too much to mount a weed whacker - although you are right the combination you've given is light and powerful. I was looking at modifying a Jetcat turbine because it seems simple enough as a DIY with shopbot help - and the noise it makes...

    Continue EV project or not? Need feedback

    Seems to me your startup is developing prototype electric motors that is clearly not applicable to the automotive space, otherwise you would keep this vehicle as your eventual halo demonstrator car. And maybe you should, rather than seek ES forum member interest to complete it. Man, you are...

    400 watts in suitcase - can it power a Collosus or bigger?

    I believe that the IHI turbine shown is a typically Japanese miniaturization demonstrator. As Dave said an impressive achievement nonetheless. But even at 140KW charging capacity (?!?- per above Jag C-X75 image for two turbines) the Bladon turbine has not seen wide spread adoption success thus...

    400 watts in suitcase - can it power a Collosus or bigger?

    Thanks Dave for sharing your knowledge. So it is tip clearance creating a larger percentage stage leakage which causes relatively weak BTU to watts conversion efficiency. When the Jag C-X75 came out with the Bladon turbine, I mistakenly thought (as many others have) that the jet noise was what...

    400 watts in suitcase - can it power a Collosus or bigger?

    Sadly the big outrunner that I have made is much larger than a Collosus. Hence my problems with rapid depletion of my battery packs. Lightness appeals to me in my application. Hopefully batteries progress soon to the point where it doesnt end up heavier than a conventional ICE vehicle - perhaps...

    400 watts in suitcase - can it power a Collosus or bigger?

    My thoughts exactly. The experimental Jaguar C-X75 has bigger Bladon microturbine generators, ... but for replenishing a battery pack that is already at 10 or 15 percent charge, this IHI microturbine would be of little use it seems. I've paused on their testing in the videos. The amps...

    400 watts in suitcase - can it power a Collosus or bigger?

    While commercially available batteries still have weight and range issues, perhaps this supposed 400 watts in a suitcase from IHI can fill the gap? Youtube video here: http://m.youtube.com/watch?v=Al8elCF816g (Note: you might have to remove the 'm' in the link if watching on a PC) My...
