That will effect the rate at which the cap dumps through L2 the Primary (low inductance few turn) in the working circuit and then through L1(high inductance) the motor coils.  I strongly feel a second coil should be added between the exit of the motor coil and the rotary gap disk to vary the inductance of the motor. This is shown in pat 568,178 .

Yes I agree, if you follow teslas patents he is making improvements on 568177. I use a 12v/120v transformer with the sides cut off to form an inductor (choke), then the sides can be moved to and from the inductor with brass screws to vary inductance quite accurately. I also use an AC commutated motor for L1 from a shop vac, it is rated at 12amps @ 120v. We should remember these AC commutated motors amp rating is based on the motor coils resistance, more resistance equals lower amp draw, so I wanted a high amp/low resistance motor which has its power varied through impulse duration/frequency not resistance---- resistance is bad.

@AC
good web link here for folks http://www.tpub.com/neets/book9/34a.htm
Just some basic ee stuff page 2 has a section on resonance and the curves showing the intersecting points of the inductive reactance and the capacitive reactance... There opposites yet when balance is achieved so is resonance.

I see two sets of motor contacts, b-b and H-H. which is for the motor and what is the other set for? Does anyone have estimated values for the capacitors and inductors? time to experiment...

[quantum1024]

and an extra set in the front for switching too ..

For simplicity, can I use a standard small dc motor with an extended insulated shaft and on this shaft put the necessary contacts on it and on the shaft.

I just posted that as refrence for folks so they could see the progression from 568177-->588178-->568179Ã,  helps when there in order and you can see the additions to the circuit.

I think you may want to look at exactly what is happening with the disk(rotary attachment with segmetnd pie insulation)in patent 568177. This has to be EXACT!!!Ã,   EG 0 and 180, 270 and 90Ã,  conductive strips have to be split into equal quadrants,Ã,  to start two conductive strips and two insulating sections will make for 2 on off cycles per rotation of the disk.


Here are the two things i see happening


1) The brushesÃ,  G on the left and K on the right complete the "Working primary circuit" every time the two brushes hit a "Conductive Strip on the disk".Ã, 


--This dumps the cap through the primary (L2) while at the same time short circuiting the motor. This "break" for the motor while the cap is dumping is what allows the current of high electromotive force is devolped for charging the capicator.

2) Now the disk at the top has brushes G and K on the "Insulating sections" not shorted and the current of high electromotive force waiting in the motor coils can be discharged and accepted by the capacitor in the Working circuit.
