F.B.D.I.S.S.M - Flux.Boosted.Dual.Induction.Split.Spiral.Motor.

The original Dual Split Spiral motor seems a little bit more powerful on paper.
I used the same magnets size and got 255,5lb thrust.
This equals to 85,16 ft-lbs. Divided by two I get 42,58 ft-lbs.

HP at 500 RPM = (42,58*2*3,14*500)/33000 = 4,05Hp = 3022 watt

And the Dual Split Spiral motor and it's Booster controller is a lot easier to build.
I have to make a design decision during this weekend.

If you split the stator segments into 3 segments instead of 2, you will not have 2 rotor arm magnets going through the sticky spot at the same time. 3 rotor magnets will be providing rotational forces each time 1 gets to the rough place....

...but you will get back the problem of hefty out of balance forces.

You are right, I didn't think of that. Thanks.

I am always interested in what you're up to. Hope your work with Jack is moving along.

What if the stator being in two parts was split 55% one half and 45% the other half.
This would eliminate the two stickies at the same time, without having to sacrifice too much on momentum. So one side would be  198 degrees and the other 162 degrees.
It's better than having three at 120 degress each.

I believe it's more difficult to balance the rotor in that configuration.

Anyway, the benefit of having the electromagnets placed equally apart, is that it really simplifies
the electronic controll. Just parallel connect the coils and hook up the wires to the Flux Booster controller.
The reflective reading forks will be mounted to see when the rotor gets in position.
When one of the rotor heads are in position, then the other one is in the equal position as well.
Then fire the Pull pulse and rise the magnet field within 200uS to attract the rotor magnet into the electro magnet area.
When getting attracted away from the last of the stator magnets, no breaking occurs and no momentum is lost.
Once in place, reverse the field of the electro magnet within 200uS and Push the rotor into next rotation cycle.
Turn of the current when the rotor is out of the electro magnet area.
In all of the Pull and Push modes of the coil, the back emf is recovered and saved to the next phase.

Regarding Jacks motor, I'm still wating on the big test coils to arrive.
A local transformer factory was nice to help me wind the 3 coils with 520 turns on each core for free.
They forgot about it and I phoned to remind them. I got an email today that they will wind them today and that I could
expect them on monday. I hope so. I really need to test the new improved features of the Flux Booster controller.

I still believe in both Jack Magnet-Valve motor and the Dual Induction Split Spiral Motor. (And of course E.M.I.L.I.E)
If there is a path to over unity, there must be several ways to bridge it.
While I'm waiting for the outcome of Jacks testing I spend some time on the FBDISSM.
It seems like the FBDISSM is more expensive to build than Jacks valve motor due to more magnets but
the air gap distance is not so crusial inside a spiral motor and this will make it easier to build.
