That's great Thane!  Very exciting to see what new experimental and theoretical possibilities this opens up.  I'm not at all surprised, as hoptoad's previous results always made it pretty clear this was not going to be just an induction motor trick.

Thanks for the video...well demonstrated as always.

THANKS JM!

I THINK THIS PUTS TO REST ALOT OF "GREY AREAS" AND OF COURSE THIS IS JUST A FIRST GO AT IT.

IN THE MORNING I WILL BE REPLACING THAT HEAVY IRON ROTOR WITH MY LIGHTER STEEL ONE AND I OUGHT TO BE ABLE TO REV UP TO 1800 RPM WHERE THE EFFECTS OF THE HIGH VOLTAGE COIL ARE MOST NOTICEABLE.

THANKS TO I_RON AND HOPTOAD FOR "PUSHING" ME WHERE I KNEW I NEEDED TO GO BUT STILL RESISTED. THANKS TO YOU JM FOR YOUR "ARTWORK" AND EVERYONE ELSE FOR THEIR ENCOURAGEMENT, SUGGESTIONS, AND COMMENTS (ESPECIALLY THE DIFFICULT ONES). AND THANKS TO LUC - THE "UNSUNG HERO" IN ALL THIS.

THIS IS REALLY GOOD INFO FOR THE X PRIZE PEOPLE.

Hi Thane,

Allright DC motor with a cool paint job. Just wondering what is the wind type of the motor, series, shunt, or compound?

Thanks, Larry

Just wondering what is the wind type of the motor, series, shunt, or compound?

I'm curious too.

If its not a shunt wound permanent magnet DC motor, its torque characteristics will produce a parabolic non linear curve.
A compound motor will exhibit the least amount of torque non linearity.

But, unlike an AC induction motor, there is no "slip" zone and no "pullout zone" and also no power factor to take into account when measuring input power.

If Thane is using DC with PWM switching to control the initial speed, then duty cycle correction must be applied to the power input measurement figures.
But I doubt Thane needs anyone to tell him that!   

@Thane : you're on more solid ground now with a DC motor. This effect worked when I did it with a pm dc shunt wound motor, it worked for nali2001 with a universal motor, and for you with an AC induction motor, so you can safely assume, now that you've also changed to a DC motor,  that the effect is in the generator, irrespective of the prime mover. Now you can concentrate on optimizing the generator, knowing beyond any doubt, that is where all the action is !

Even better, now you can set up two systems side by side, and demonstrate that to the profs and EE's, etc, in real time.
Your generator is the perepetia, the motor is just a mover.
Show them the AC induction system first, let them react and put their opinions out there, then unveil the DC system and see there reaction again.

KneeDeep ... Wish I could be there with a camera

IT IS CAPABLE OF ALL THREE BUT IT IS IN SERIES MODE IN THE VIDEO.

THE BEST PART FOR ME IS IT OPENS THE DOOR TO ELECTRIC CAR MANUFACTURERS WHO USE DC MOTORS - NOW THEY CAN SEE THAT THE GENERATOR WILL WORK IN THEIR VEHICLES.

OPTIMIZING AS WE SPEAK!

If Thane is using DC with PWM switching to control the initial speed, then duty cycle correction must be applied to the power input measurement figures.

RIGHT NOW I AM SIMPLY FOCUSING ON CONVENTIONAL LOAD INDUCED DECELERATION AND ACCELERATION AS PROVIDED BY THE HV COIL.

IS WISH YOU ALL COULD BE THERE - WE WILL HAVE TO MEET IN THE MIDDLE OF THE WORLD SOMETIME AND GET TOGETHER. I'M BUYING!
