I THINK IT IS SAFE TO PUT THE "SHORTED HV COIL CAUSING ACCELERATION BY REDUCING CORE LOSS THEORY" TO BED NOW - BUT EVEN IF IT WASN'T - ANY LOSS REDUCTION IS A BENEFIT.

Good news Mr Tee, The cups came this afternoon!  I hope they didn't push the dogs too hard?
Couple places near the end of the run here where there is no snow, pretty rough sledding...

Anyway, the pieces seemed to fit the ugly one and managed to stay in place at 3600 RPM.

Just a conventional coil in the test... the old rotor with 12 magnets in six stations put out 47 volts.

MY rotor with the 18 magnets in 18 stations pumped out 99.2 volts,( with the plastic surround!)

YOUR new rotor only managed a dismal 90.7 volts

So there is what, 10% improvement with the 1 1/4 OD cup and plastic surround?

Shown here at speed but stopped by the flash... Canon A590, love it

I will need an addy for shipping... don't want this cluttering up the shop, lol

THAT'S REALLY NICE WORK THERE RON!
I WILL TAKE THE UGLY ONE ANY DAY OF THE WEEK!
I CAN'T WAIT TO TAKE MY NEW ROTOR TO CALIFORNIA WHEN I GO.  

THE ONLY PROBLEM IS IT MAKES ME SHY TO SHOW MY WORK. 
HERE IS MY NEW LEXAN ROTOR & CORES.

THANKS

Your new rotors are not too shabby?  Looks pretty good, like the plastic around the magnets, 

How fast you bin running them?

Ron

Edit: more to the point, how does the output compare between the Lexan and Barrow?

AFTER SEEING LUC'S EXPLODING RAZOR SHARP PLEXI-GLASS ROTOR FROM HELL - I AM A NERVOUS NELLY, SO I HAVE NOT GONE ABOVE 1600 RPM.

I STILL THINK THE STEEL ROTOR IS SUPERIOR AND I AM HAVING ANOTHER BARROW ROTOR WELDED TO SEE FIRST HAND.

THE STEEL ROTOR CONNECTED TO THE STEEL MOTOR & AND I_RON BASE ATTRACTS THE HV COILS DELAYED FIELD AND IMPROVES PERFORMANCE IN MY VIEW - BUT WE WILL SEE SOON.

YOUR ROTOR IS SIMPLY THE ICING ON THE CAKE!

WHAT I WAS TESTING TODAY WAS VARIOUS WIRE GAUGES 26, 28, & 30 GAUGE.

Better to be safe than sorry....

Butt you could run each at say 1600 and record the output with the same coil

Or you could send a motor and rotor to the PM and/or the defense minister and ask them to run
it up to an over speed condition for you, as to certify it was safe?
