JB Zero Force Motor - anyone building?

[Pirate88179]

Hi Bill,
  When YouTube went to the Google Plus it just made life more difficult.  Some people got so frustrated with it they just faded away.  Speaking of that has anyone heard how Jeanna is doing?  I know that she went out in the wilderness a few years ago and built a small place.  Her channel is still up at YouTube but not much activity.

Yes, I have not upload much lately over there.

As far as Jeanna goes, the last I heard what what you have said.  She told me no grid, no internet where she was moving to out in the woods so, that was a long time ago and I have no idea how she is doing.  It would be great if she popped in from time to time to say hello.  I hope she is doing OK out there.

Stefan suggested that I take a look at Ben's (K4EZP) pulse motor called the "Thomas Motor".  I vaguely remember it but I am going to build one up today and look at it.  He uses a  ferrite toroid cored coil with a permanent magnet inside the toroid.  Ben did a series of videos on it but this is the one that shows how it works:

  As I read more it seems that TK you played around a lot with this ORBO type motor.  I guess this is another ancient history item that is just new to me.

I for one am very happy that you are posting here Lidmotor,and i always look forward to see what you have come up with next.

I have been thinking about what the best configuration of coil would be for a pulse motor,and i think it would be one where the run coil produces no EMF,but the trigger coil would have to-to fire the transistor. After watching that video you posted above,i think i have a design that will do just that. So im off to the workshop to try it out.

Looking forward to your findings on the above setup.

Anyway,here is my final video on the Zero force motor.

Here is my quick build of Ben's 'Thomas Motor'.  I was able to get the motor to run with the coil windings parallel to the rotor magnets.  The small neo inside the ferrite made it possible.  No magic but interesting.

Tinman I was sorry to see that your motor didn't improve with the iron cores.  The whole geometry of this weird type of motor just seems wrong.

Yes,it was interesting to see the iron cores had a negative effect,but the motor design is not very good at all. I think it's a case of the JB camp running out of new idea's ?,so there just throwing together anything that is odd in design but will run-even if very inefficient.

Im thinking the old vacuum cleaner (hoover i think you guy's call them over there)motor(universal motor) would make a good strong pulse motor--will have to look into that one.

Time to look at this version again from kEhYo:

Partial description;

"The stack of magnets behind the driving coil is in opposition to the rotor. When the driving transistor shuts off, the magnetic field from this stack pushes the rotor away from the TDC".

https://www.youtube.com/watch?v=9UlwdLXO3AI

"A Hall sensor turns on a MOSFET transistor on an approaching magnet to neutralize repelling force from the stack of magnets behind the driving coils that push the rotor at Top Dead Center when the power is off. In that moment the coil becomes a generator coil as the core (magnetite powder + iron powder + resin) switches polarity and returns much of the energy back to the battery".
