PM 3-phase machines are my bred and butter, near every day, years to years.  I do order high grade high temp. special shape magnets from Germany, photo-etching gut stator laminations 0.18mm from UK, 7075 aluminium from Holland  - all the rest I do myself ... oh yes, anodizinds I do order from local shop.  I have great workshop wheres all what I need, included cnc machines, two plane precision balancing machine, test stands ... legal and paid soft, all tools and instruments, meters ... huge lot of stuff at screws to electronics ... all, all, all ... no needs to visit any shops for years.
For one thing I wind motors and generators, I hope you understood. Someone is speaking that stranded wire gives out more Volts than solid 
Oh boy    I use solid wire, stranded, different brands of Litz ... I can wind with solid or with Litz - only number of turns does matter - this is fact. Number of turns gives Voltage, wire diameter gives Amperage. The same outer diameter Litz handles less current than the same diameter solid wire - this is also fact.
Litz or stranded wire is inescapable when air core motor. When iron core motor then you can use Litz or stranded but not necessarily. Litz and stranded are easier to wind - this is also fact and this is because most of RC motors are wound with stranded wire or some use even Litz, like Plettenberg. You can use Litz when hoping top of top efficiency, but about high efficiency we can speak after all other conditions are accomplished, for example core material and perfect shape, magnets ... large solid magnet causes losses, better to be shaped and segmented, perfect well-founded air gap ... in some case we have higher motor speed ... like >50.000 RPM  and high freq. switchings speed control ... ... so, after all mentioned we can speak we use Litz because higher efficient, otherwise we use Litz because we just have this Litz and this is easy to wind ... or just horse around, playing big polymath 
I need to test my machines. I have two special test stands with driving motor. Driving motors are verified - 92% efficiency. I have measured  in-out voltages, amperages to be bored. Now this is is computerised but manually I do it as well. I can measure like this or like that, I have perhaps hundred DC/DC converters, I can control RPM by what ever graphs ...  but ... I never find even smallest possibilities for honest selfrun
cheers,

Observation:  It is not the RPM that induces the voltage it is the rate of change of flux.

Question:  Is there a way of having the rotor magnet move closer to the core of an induction coil without the core seeing a large percentage of the field.

What I did a long time ago was to use a like pole on one side of the core, a washer on the other side that faced the moving magnet and allowed for a small load to be taken from the coil  while the magnet was moving closer.  The effect of the washer was to give a small rise in induction which would drive the field up in the core, or pulling more of the fixed magnets field down and through the core, as well as the washer had a larger hole in it and I have noticed that magnetic fields tend to bend around the hole, all of this, in my thoughts, were hiding the core from the moving magnet until the distance was very close and then the field from the moving magnet would burst into the core.

What I was thinking with all this was that when the coil started to produce the current flow almost all of the flux lines would now be parallel to the core and when the burst field hit it would snap the flux lines perpendicular to the core giving a very fast flux change and therefore more voltage as well as if I could ever get the core values and timing just right the the burst would help to repel the moving magnet from the core in the direction of rotation.  I called this one my peek-a-boo generator, it kind of worked most of the time and some of the time it ran itself for a while but nothing as good as what R achieved.

Webby1,

please, post more like this. Very observant of you. So your conclusions were based on the final detail of the law's of induction? So you concentrated not only the flux but also the total TIME? Very clever.

More we study this thing more it corroborate what Romero has done. In every detail.

Thank you,

Fausto.

No sorry, I only downloaded these last 3 of his movies.

Maybe someone else still has it and can post it again ?

I have the one he called something like "10x OU". Tried to post it back up on YT, and they blocked it because they say it's too long. Odd, since that's where I grabbed it from.

Do you have that one? Let me know if it's one of the missing vids and where I should upload it to. 

Cheers,
