@Zerofossilfuel: LOL "At 88 MPH your gonna see some serious $hit!"
Z, If you have built your rig as per Romero at 200mm diam...20mm mags..4mm from edge..4875rpm=114.2mph edge speed! Centerline of mags 98.2 mph! You're 10.2 mph over your speed objective! LOL. if you want 88 mph edge speed..you want 3757rpm..centerline 88 mph of magnets, you want 4368 rpm.
SORRY. This was just for $hitz and giggles. John

PS. (Very important...) DO NOT FORGET THE 25uf FLUX CAPACITORS

A fantastic book on magnetism ( hard core )

What is he talking about? Absence of magnetic lag?

I did a small experiment today involving bifilar windings . Someone else posted a link to a website about this . I made 3 electromagnets using 3 similar iron cores . Each magnet used the same length of wire . One was wound normally , one bifilar and one quadrifilar .The same power supply was used to test each electromagnet in turn . The strength of each was tested by seeing how many small nails it would lift . The results were as follows .
Normall wind- 4nails .
Bifilar wound - 12 nails .
Quadrifilar ,12 nails .
    Note that each electromagnet had the same core and the same Amp-turns .I was surprised that quadrifilar was no better than bifilar . This experiment seems ridiculous , but you MUST do it yourself . The implication is that by using a bifilar motor coil , you could create the same input torque for a much lower electrical input , maybe as low as one third . Got to be worth a try? But do the simple experiment first .

I have mapped those figures according my understanding and have seen that there is a always a trade off upon this effect and no energy gain. I openly seek an experimenter here to post his experience that a shorted and accelarating coil will make a net possitive effect. No luck so far. Romero himself told that someone should demonstrate that effect. It would be a milestone. Yet, despite several accelarating setups, do not think anyone has a net energy gain.

I can confirm your results exactly.

I joined Thane at about the time gotoluc was winding the multi strand coils and as you know, built several rotors for Thane. I could never get him to establish a base line measurement which showed that all coil shorting was doing was to reduce core drag. Shorting a coil collapses the flux field, pure and simple. Ergo, reduced drag can be the cause of acceleration. Thane has grown smarter over the years, moved away from having the flux flow down the broom handle across the table and into the motor (humor) but you must remember he thought and based all his theories at one time on peak voltage at TDC. And refused to budge from this for the longest time, even after I posted a single magnet coil/core scope shot showing the resultant sine wave in such a situation. I have not followed his latest work so have no explanation for his "self runner" vid etc.

thanks, neptune - interesting

approx how many layers & how many turns per layer on the normal e/m?
