Test drive @ 3500 rpm  ... my hands were shaking there for a second at one moment .. scary to be around without any safety mount and cage.

P.S. That cracking sound you hear at the beggining and all the way thru is my coffee maker sorry... rofl

Great job. You seem to have it perfectly balanced as there appeared to be very little movement of the Ryobi at such high speed. You really should have a safety cage around it. When I was trying to replicate the Whipmag I was using just the air off an air compressor to test spin it up and I still can not find the magnet that broke free and missed my head by inches before bouncing around the room. My test spin was not going anywhere near the speed your Roybi was running so you can expect very large holes in your house walls or body if one magnet was to break free.

BUT HE CAN REALLY PLAY THE GUITAR AND SING WELL - ALTHOUGH NOT AS WELL AS YOUR ROTOR AT 3500 RPM - BUT PLEASE PLAY SAFE!

Nice MINDE!

well done.

It's also time to proceed experimenting with coil arrangements, gauges, parallel windings etc etc. Its good to see the rotor of yours resembling Mr T's rotor from the very beggining. Mine as you know was not since i tend to proceed from elementary to more complex designs by seeing and learning in the process (it's a curse actually! Too much cost)
..........................................................

I saw you are in search for laminations + coils.Those are pain in the neck Mine are ordered and coming from the far America Continent ) . After some thought those are going to be of two kinds for experimenting.

One relative short and thick http://www.erseaudio.com/Products/IXQCoils16Gauge/ELC55-16-1000

Another long and norrow. http://www.erseaudio.com/Products/IXQCoils16Gauge/ELC56-16-5600
(of course they must be rewired)

I am really curious to see Mr T's effect on those different coil's geometries.

ps: rotor noise come from interaction of air and rotor cavities. My rotor form machined alluminum at 1500 rpm (without any coil around) is not even heard, only the damned bearings

Ok, while waiting parts to arive and new action taken i sit back and theorizing just a litte bit.

I want your views regarding Magnetic Field Distortion effects and their relation to (as primary or secondary factor perhaps) to Peripeteia design.

See wikipedia for an initiation on this effect. I was completely unaware that this effect was actually existed. Now it complicates my simple so far view of what happens when bringing close a magnet to a coil.

http://en.wikipedia.org/wiki/Brushed_DC_electric_motor

Note the implications of the effect are Voltage / current curves to be totally incosistent to physical magnet possition in relation to coil, as well as others that i cannot think at the moment.
