Sounds a bit sleazebagish. If anyone had experimentation tools we would be visiting other galaxies by now. Either get off that dildo you "accidentally" sat on and shut your trap or start building a lab.

Sure, just send me the funding so I'm not just living from pay to pay.Sheesh - We don't all have access to labs, equipment or the funding for both. Thane is already set up to run any number of minor tests.
By the way, your own comments are a prime example of sleaze.

JUSTME, NICE TO HEAR FROM YOU AFTER ALL THIS TIME - I FIGURED YOU MOVED TO NEW ZEALAND AND STARTED MAKING BABIES WITH A22 OR SOMETHING?
AND WHAT THE HECK ARE YOU DOING HERE ANYWAY  IF YOU ARE NOT MAKING BABIES YOU CERTAINLY OUGHT TO BE DOING SOMETHING ABOUT YOUR FREACKIN' SENS.  OR ELSE WE WILL ALL HAVE TO LEAVE TOWN FOR SHAME.

I HOPE ALL IS WELL WITH YOU!

CHEERS

Nope! Still here, still keeping up with the thread and hoping all this comes to something interesting and applicabale both because of your work and in spite of it. 

I love my Sens, still.  Even though.

Yes, you are correct, take the rotor off... This then becomes a first baseline.

In my case the motor sans rotor, runs on 80.5 volts @ .57 amps = 46 watts.(3569 rpm)
Now I know that the rotor uses 50 watts to run... if I changed rotors then I would have a baseline
to know IF the new rotor used more or less.You could do the same thing... how much does the
open barrow rotor use? how much does the windage cost?  how much does the #2 rotor use?

Incidentally, it also points out that the Ryobi, running with no load on line voltage, is not that efficient.
On 117 volts it uses .92 amps, wow, 107 watts! (no rotor! 3580 rpm)

GOOD USEFUL NUMBERS.

Butt Thane, this first baseline is only of use if you were comparing rotors. To compare coil/cores
it is most useful to put the baseline at having the rotor on the motor. Then you don't have to make
up stories... you said on list that the new rotor would barely get to 1000 rpm in CA, Owen told me
the same thing, why then say that it did run fine but then change the scene to Ottawa ... with the
new core material?  Here is something we would all be interested in... what is the core drag
reduction with the new core material? Grab yourself a proper baseline and tell us!

BARELY GET TO 1000 RPM DEPENDING ON AIR GAP... AND CRAPPY CORE, AND HUGE EDDY CURRENT LOSSES IN COIL MOUNTING MATERIAL.

OTTAWA SCENE: NEW CORE W/ NO CRAPPY EDDY CAUSING STEEL = GREAT RESULTS.

what is the core drag reduction with the new core material?

WHO KNOWS THERE ARE AN INFINITE NUMBER OF VARIABLES SUCH AS AIR GAP AND SO ON.

At least tell us the specs on the new material... I remember you saying you were going to send me some... that it was in a box all ready to ship....Ron

YES IT IS STILL IN THE BOX WAITING FOR YOU TO TELL ME YOU WANT IT?

Sure, just send me your tools, your workshop, your motor and rotor and measuring equipment. Oh, and don't forget the coils/cores.
Cheers

DEAL!
BUT YOU HAVE TO TAKE ME AS WELL...
- MY WIFE CALLED ME A WORKAHOLIC - SO I WISH I HAD THE TIME YOU ALL THINK I HAVE.

Can someone provide a plot summary for the 438 pages of this thread?

Thanks in advanced!
