Well done Jack, I wish you well and once again well done.

JackH,

You're a bloody legend mate. 

To see you offer up the info like that...well...it was a moment of greatness on your part. 

Thanks for that, and good luck with it all.

Les.

Jack Hilden-Brand recently measured around 2x over-unity in his electromagnetic motor design, which closely resembles the Joseph Flynn parallel path concept.

A friend emailed me the following statements:

"It appears that Joe Flynn's Parallel Path patent covers what
Hilden-Brand has done.
So if Hilden-Brand tries to patent it he will run into Flynn's patent.

Also, an FYI, Joe Flynn's Parallel Path motor is being used and built by
Boeing and also by Seagate for hard disk drive motors.

It's real.  I have done a ton of FEMM simulations on different variations
of this approach.  I can verify that the expected efficiency is around 200%
up to about 250% without friction and windage or other losses taken into
account.   If you consider that a typical variable reluctance or switched
reluctance motor is around 90% efficient the 2x improvement would result
in an efficiency of about 180% taking a standard SRM as a reference.

I just wanted you to know that it is a real phenomenon.  The first case of
this being seen is at this Japanese site (circa 1995, [see "Profile" page).

I independently verified the curve you see in Figure 5 with FEMM
simulation runs
before I saw this site.

So Hilden-Brand has invented the same thing as what this site shows, but
10 years
later.  His form is a bit different, but essentially the same in
principle.  It's good to
see another confirmation of the approach.  Hilden-Brand's is pretty
creative actually.
I hadn't thought of using the magnet and coil in the same volume.  However,
he would have a micro gap between the coil core and the rest of the magnetic
circuit.  That can result in a bit of flux leakage to the rotor that
might not be
desireable."

So far the comment from a friend who is a very schooled specialist in FEMM
simulations.
Anyway, it is nice to see some confirmations this way !
Jack has really brought out something very useful !

I am sure Jack will get his patent, for 2 reasons:

1) Jack's design is sufficiently different from Flynn's:
a) Jack uses only one magnet, Flynn uses two
b) Jack uses one coil that surrounds the magnet, Flynn's uses 2 coils, and they don't surround the magnet

The end results, if both were put into black boxes, would be very similar. As far as the overall efficiency of each, I still need to go do some simulations with either FEMM or Ansoft Maxwell SV. It will be interesting to see if one comes out ahead, or if they are dead even.

2) Patents do little or nothing in protecting intellectual property rights of the owner, and patents that are so similar to each other are being granted every day. IMO, patents are a waste of time, effort, money, stress and lawsuits.

All the same, I wish you luck Jack.
