PB might still be male.

True, still, I think I'd rather be absolutely sure I had the right victim before I "carped" them.    .......  If I were going to, which I wouldn't anyway......   

NO DOUBT PB's HUBBY WOULD ENJOY A GOOD CARPING - AFTER DEBATING QUESTIONS WITH PB  I OFTEN CARP MY HEAD AGAINST A BRICK WALL UNTIL I PASS OUT.

Haha LMAO here 

Got the coil fixed I'm looking for a place where i can order ferrite, any one got a clue, couldn't find what i was looking for.
Ordered new rolls of wire, the rest we got in stock.
Cheers

USE WELDING RODS.

HELP STOP WMD"s
WARMONGERS OF MASS DECEPTION

YOU ARE EITHER WITH US OR AGAINST US HOPTOAD...
THOSE FROGS LEGS OF YOURS WOULD GO NICELY WITH MY FREEDOM FRIES.

Shorting the coil reduces the magnetization in the core, by Lenz's law, and therefore reduces all of these losses.

Try shorting the coils in any normal closed magnetic system generator or alternator while it is running at normal operational speed and SEE WHAT HAPPENS. Lenz's Law will create a breaking effect on short circuit that can bring the driving motor to a standstill, resulting in increased driver motor current consumption and losses!

The accelerating "effect" currently being studied is only apparent in open generating systems. It has nothing to do with the motor, and everything to do with the generator. Open Magnetic Systems are the key.

This "effect" will be much easier to measure and understand by switching to high speed pmDC motors as the driver, because their torque versus rpm relationship and the current / voltage versus rpm relationship is linear and therefore easy to predict, understand and measure.

Also run the drive motors at full throttle, not in a constricted mode way below their normal operating parameters. This will make power consumption figures easy to measure, and output power will be at a usuable practical level. Measurement errors will be minimal, if working in tens of watts, instead of micro to milliwatts.

Induction motors in particular, do not have flat responses to varying loads under normal operating conditions, let alone when they are deliberately hobbled by current and voltage supply restriction. IMHO, induction motors are a poor choice for use in these experiments.

Also, DC rectify and filter with an electrolytic cap, the O/P of the coil/s (for more accurate O/P measurement under load) and feed it through incremental resistive loads up to and including S/C and you will find that the normally expected breaking effect is not linear as in a closed system, but non linear. At a particular current the breaking effect will cease to increase with increasing load, and instead will decrease (the perceived acceleration effect). The O/P current required for the effect to "kick in", in any given coil configuration, is dependent on the impedance of the coil/s (at a given frequency - i.e. rpm) and the length of the core/s.

Higher (but not necessarily high) impedance coils on long cores will begin to exhibit the effect at a lower frequency (RPM) than lower impedance coils on short cores. Coils which are only wound on 20-25 % of the core length at the end closest to the magnet, will also show a greater "effect" at lower rpm as well.

I found the effect to be very beneficial and useful in my own alternator experiments in 2001-2002. However useful, it will not cause the driving motor to run faster, or exhibit greater torque, than it would without the generator attached at all. It is not an O/U effect, it is a counter mmf phase change effect, which is still very useful.

Cheers all.

LUC AND I HAVE SPENT THE LAST 2 DAYS BENCH TESTING 2 PM BRUSHED DC MOTORS WITH NO ACCELERATION AT ALL.

TODAY I WILL COUPLE THE DC MOTOR TO THE DRIVE SHAFT OF MY INDUCTION MOTOR SO I CAN USE IT AS A GENERATOR AND PROVIDE DEFINITE DATA ON HOW MUCH ENERGY IS BEING PRODUCED BY THE MAGNETICALLY COUPLED GENERATOR DURING ACCELERATION.

HAS ANYONE TRIED THIS WITH A BRUSHLESS DC MOTOR?
THIS IS OUR NEXT STEP.

SURE PLEASE COME FOR A DEMO AT YOUR CONVENIENCE - ON YOUR WAY CAN YOU PLEASE STOP BY POLAR BREEZE'S HOUSE AND BEAT THE CARP OUT OF HIM - TIE HIM UP - GAG HIM AND BRING HIM ALONG AS WELL - LUC AND I WILL FED EX HIM TO HOLLAND AFTER THE DEMO SO YOU WON'T HAVE TO DRIVE HIM HOME.

THANKS
Thane

I have my fun and will stay on this thread.

thanks   you made me a nice day
