QuoteWouldn't the back emf (or released current) of the high impedance coil induce a flux in the low impedance coils and cancel out some of their output?

YES IT DOES IF YOU DO IT WRONG - BUT AS HP POINTED OUT - THE DELAYED INDUCED FIELD OF THE HIGH IMPEDANCE COIL RELEASES JUST BEFORE THE MAGNET MOVES AWAY FROM T.D.C..

SO IF YOU HAVE AT TDC

CORE SOUTH
CORE NORTH
CORE SOUTH

THEN YOU HAVE AS MAGNETS MOVE AWAY

CORE                        NORTH (APPRAOCHING)
CORE NORTH (DISCHAGING)
CORE                         NORTH (APPROACHING)

NOTE: A SOUTH POLE MOVING AWAY = NORTH POLE APPROACHING

SO YOU CAN SEE FROM THE ABOVE THAT - WHEN THE SOUTH POLE MAGNETS ARE MOVING AWAY - THE DIRECTION OF THE MAGNETIC FIELD INSIDE THE HIGH IMPEDANCE CORES IS THE SAME AS IF A NORTH POLE MAGNET WAS APPRAOCHING.

THE DISCHARGING DELAYED INDUCED NORTH POLE FROM THE HIGH IMPEDANCE (CENTRE) COIL:

1) PUSHES AWAY THE NOW RECEDING NORTH POLE (CENTRE) MAGNET -
2) ENTERS THE HIGH IMPEDANCE CORES (INCREASING THE NORTH POLE FLUX MAGNITUDE)
3) ATTRACTS THE APPROACHING SOUTH POLE MAGNET ON THE ROTOR. (THIS MAY HAVE A MINIMUM EFFECT BECAUSE THE DISCHARGING HIGH IMPEDANCE FIELD WOULD ATTRACT BOTH SOUTH POLE MAGNETS BACK TO THE CENTRE CORE - PREVIOUSLY MY TOP CORE DESIGNS PROTRUDED OUT FARTHER THAN THE BOTTOM CORE TO ENCOURAGE FLUX TO GO THE TOP ROUTE INSTEAD OF THE BOTTOM.

ALSO - NONE OF THIS WORKS IF THE LOW IMPEDANCE / HC COIL CORES ARE TO OMITTED...

Good to know. One last thing, what happens when you unplug the input at a certain RPM, shouldn't it technically keep running seeing how little the input is helping out.

MAYBE - MAYBE NOT?
YOU WOULD REQUIRE A VERY POWERFULL HV COIL.
BUT AS YOU CAN SEE FROM THE NASA VID #3 THE MOTOR IS NOT OFFERING MUCH TORQUE.

YESTERDAY I WAS ACCELERATING MY NEW "E" HV COIL AT ABOVE 1600 RPM WITH THE MOTOR INPUT AT 55 VOLTS - SO AS THE HV COIL GETS STRONGER THE MOTOR INPUT REQUIRED GETS LESS AND LESS.

Hi Thane,

what about torque, does it also become less and less?
Remember, Power = torque * angular speed
If rpm increases, torque should decrease, but does that happen in your experiments?

Outstanding new coil results T!

My last testing from this earlier this year when we were using separate HV/HC coils was only getting 1700 RPM at 120 volts with half as many magnets on the rotor.

That coil is working like a supercharger.

AT 55 VOLTS TO THE MOTOR THE TORQUE SUPPLIED BY THE MOTOR IS LESS THAN WHAT IS REQUIRED TO TURN THE ROTOR AT 100 RPM.

FROM 100 RPM TO 1600 RPM THE TORQUE REQUIRED IS SUPPLIED BY THE HV COIL.
OR
THE HV COIL IS ELIMINATING CORE LOSSES AND THE MOTOR IS ACCELERATING THE ROTOR
WHICH IS SIMPLY IDIOTIC TO ANYONE WHO HAS SEEN IT AND DOES NOT USE FLUORIDE TOOTHPASTE.
