@Nali2001
Finally someone achieving similar results to my own. Acceleration with a useful O/P, without resorting to complete short circuit to achieve that acceleration.

Is that a universal motor you're using in your video?
Is it a single O/P coil assembly?
What is the DC resistance of the coil?
Do you know what the inductance of the coil is?
How many magnet pairs on the rotor?
Have you tried incremental loading to see what the minimum amount of O/P power is required from your coil for the acceleration to kick in?
Have you actually measured the voltage/current and therefore O/P power from the coil during loading by the globe?
Have you measured (electrical) I/P power in relation to O/P power to determine total (electrical) system transfer efficiency?

Lot's of questions, I know, but empirical data is desireable in order to develop a greater understanding of the effect.

Cheers and KneeDeep.

Hi there Hoptoad,
-Yes that is a 'universal motor' It's from a washing machine and unlike these induction motor they can be 'truly' be set to any rpm.
-Hmm o/p coil? Not sure what you mean. See the attached pictures below.
-There are two coils in parallel and each is 2.3 ohm (20Gauge wire)
-Well the rotor is a double rotor as seen on the pictures. 6 magnets 'pairs' or 12 magnets total (one magnet is 20x40x10mm)
-With this design that acceleration always kicks in as far as I know. I did make another core model and that indeed required at least an 700rpm+ before acceleration happens.

Well the big dumper is that although the acceleration is cool and all. It is only a ?relief? on the eddy drag and such the core sets up to the motor in the first place. I never found a combination where the acceleration (in watts) was more than the drag (in watts) induced due to the solid steel. I mean don't freaking underestimate the eddy currents (and such) in solid steel, it's huge. In this model each core introduces like 50watts+ of eddy currents drag. And in any sensible generator the core must obviously induce more output power then the amount of drag loses, it's own core causes. In his system you see like 50watts out and the motor is pulling like 300 watts. So if you look at it this way the generator has no output. The presents of the core costs like 50watts drag and such, but it outputs also like 50wattt So there is no net gain/output.
Plus the core got freaking hot I tell you. In like 2 minutes the cores are like 70 degrees Celsius. So you say use laminated cores then, well I did and indeed they have 10 times less drag losses and have great output, far exceeding the max output of the solid steel cores. BUT the acceleration is also totally gone. And the thing acts like a normal generator. Load it, and it loads the prime mover down. So in the mean time I have come up with the conclusion. ?Yes you can have a under load accelerating machine, but (in watts) it will only accelerate up to the point that it equals the core drag losses (in watts)?.

THIS SMELLS LIKE A VERY CAREFULLY PLANNED ATTEMPT TO DERAIL THIS THREAD BUT FORTUNATELY - I (AND I_RON) HAVE BEEN USING LAMINATED CORES FOR QUITE SOME TIME NOW AND:

THE ACCELERATION IS NOT TOTALLY GONE

AND THE THING DOES NOT ACT LIKE A NORMAL GENERATOR

LOADING THE GENERATOR DOES NOT LOAD THE PRIME MOVER

IT WILL ACCELERATE BEYOND THE POINT EQUAL TO CORE DRAG LOSSES.

NICE TRY THERE SCUMBAG!
TRY AGAIN...

Well, Crankypants, this thread can be neither collaborative or constructive if there's nobody left on it.

It seems to me that people who do different experiments with different setups and get different results shouldn't be viewed as the enemy. It's all instructive.
