I tried a deceleration experiment again with the new rotor, the result is still inconclusive...

rpm 2870-2875 (sometimes it goes right to 2875 other time it won't budge above 2870)

open   shorted (in later tests only shorted while rotor is at decent speed)
1103   1196
1042   1052
...

To me those results seem too small to account for the acceleration noted when the motor is running, that can turn a deceleration into a relatively robust acceleration but I feel unconvinced either way by these results.

A22, the experiment as I see it needs to be a little different from that. To set a baseline you first need to measure the deceleration with the coils removed completely. The task will then be to find some coil configuration (open, short, whatever) which reduces that deceleration. If you find such a configuration, this provides proof that extra power is being delivered by the generator. If you can find no such configuration, that suggests that the generator is not providing extra power - leaving open the possibility of your theory about the motor being the source.

THIS WEEKEND I WILL BE CONSTRUCTING A "MODIFIED PRONY BRAKE" WITH A DIGITAL KITCHEN SCALE AND A LEVER WHICH APPLIES PRESSURE TO THE MOTOR DRIVE SHAFT BY ADDING WEIGHT TO THE SCALE.

I WILL SHOW HOW MANY KILOS/POUNDS IT TAKES TO DECELERATE THE SYSTEM AND STOP IT COMPLETELY - NO COILS INVOLVED.

THEN I WILL ENGAGE THE HV COILS WITH THE SAME WEIGHT MOTOR I/P ETC AND SHOW HOW MUCH THE HV COILS CAN "POWER THROUGH".

BADDA BING - BADDA BOOM!

I'd always thought you folks across the pond were a little nutty - I suppose it must be those cold winters...

And your specific disagreements with his analysis are what exactly?



PS  Ever think so hard about 'those cold winters' it feels like you're right there?

My disagreement is that it does not eliminate the motor as a variable in the experiment. The results of the experiment that he is proposing will be inconclusive (as usual!).
