Interesting free energy experiment.

Hi Tinman,

I would think it would work great with a homemade driver so each pulse could recover BEMF as the motor is running.

You could arrange the coil to run on lower voltage, don't know how many volts they use, but it's a dc pulse motor and maybe it could do better then a hub motor.

What a voltage they run on?

Tom.

There are 4 types-or series as we call them,then ther is the cogless ones as well,which make great wind generators. I will provide a link below for a video that explains the difference between them,but basically it's the voltage the motors run on. The early ones use low voltage motor's,which is nothing more than wires size and turn amounts per coil. The later models run on a higher voltage,and so have more turns per coil using smaller gauge wire.
I would look for a 100 or 80 series,as these were the lower voltage motors,and easier to parallel the windings to run them on 12 volts.

I would keep using AC to run them,as there a push/pull motor,and running them on pulsed DC causes a large drop in torque.

im not sure if you have fisher and paykel washing machines over ther,but maytag and whirlpool also use them-the smart drive motor.

Motors come in many flavors, just about all can be used in various designs. One personal favorite is low rpm high voltage PMAC ... aka DC brushless. (see small photos of 11.8kw liquid cooled 600v 600rpm used in the "evidence" photo of yesterday & not put back up since)

BEMF recovery I've learned does indeed help but is not an absolute requirement, and you don't need to build it - save yourself TIME and just buy what you need. "They already exist".

I encourage you to take your TIME and read this on Engines vs. EN-GEN's http://www.backgauges.com/Gen-E-Sys%20II/en-gen.html - in it you will find it supplements what TINMAN wrote above.

On that page please notice the "The PMS 120 7kW is a very efficient motor, they are real and out there for you." Also a brushless used in my many designs/builds/research. With more to "share" it is all about TIME

Like DR WHO wrote: "unity first".

Hi Tommey,

This is just an idea.

Get rid of the generator and turn the flywheel into the actual generator by using facing angled magnets on the perimeter. This is something I've been playing with, with interesting results. It's not new there are many patents that show a similar structure for reducing driving torque. I've attached a pic of my simple prototypes the larger one performs the best. By best I mean shorting out the generator coil (with iron core) and spinning barely cogs the rotor, even better with air core as your only dealing with friction losses and boundary effects.

Here are a couple patents of similar structure, there are many more if you search around.

HI Dream,

I think the real problem is magnet flux becomes weaker due to the angle.

The stronger the field the better the output, and greater input load.

I believe this magnet design I came up with might work even better.

It called a total flux generator with some moving parts.

Hi Tom,

I made a quick test to show the effect I'm seeing. Most conventional generators I have just stop after the motor is shut off with a load, this design will coast down. The output is reduced compared to a standard design but the trade off is being able to use a smaller motor at a higher rpm with a longer spin down time while still attached to the load.

I like your belt design, would those be ring magnets with a cable through the middle?
