 "As far as I have understood, you are proposing a method to increase the efficiency to excite the electromagnets without needing the resistors array (and then saving the heat dissipated in those). Am I right?

   The resister array doesnt block off the current in the same way a resister would in a normal circuit. It directs it to one or the other inducer but always it has someplace to go with little resistance. The internal resistance of a battery if that is what is used to start it depending on design still has to follow the rule of the device having slightly more resistance then the source. The method I described as the one I prefer. Uses the length of winding in total broken into groups to act the same way as the resister array but the commutator is still required as  it controls the timing of the brush sets connected to the taps of the coil groups. Which works the same as the resistance being placed between multiple brushes.

Are your proposing an electromagnet composed of several independent coils that you are firing sequentially to increase the magnetic field?

   Sort of ,Im not sure on your meaning of sequentially. If there are 7 layers of turns with ten turns per layer and each layer has a tap but it made up of a single conductor through out. Each tap would come on in order until all of them were on and then go off in the opposite order one at a time. If that is what you are saying then yes. The actual effect is inverse but from the observers point of view it will look like it happened the other way.The observer being the Y coil. Imagine your source is 4 volts again but your using a coil built to be used with a 120 volts ac. 4 volts will produce a very week magnetic field across the entire length of wire used for the coil. the taps shorten the length of the wire increasing the voltage per turn without increasing the voltage source.On the other hand I can combine taps and change the voltage to any multiple of the value within the groups the same as a multi voltage transformer uses it's output taps.

In that case you are increasing the efficiency of the input current? It is an optimization. I suppose that Figuera just used the resistors."

 He did not limit himself to the resisters at all he used it to describe the principle of operation for ease of comprehension. I can only imagine what he would be saying today watching this. Im sure it would be colorful. I would not call it an optimization exactly. The same amount of current has to traverse each turn of the coil as would have if the coil was powered from its ends like normal. The difference is that by subdividing the coil so a lower voltage can be used to get the same effect through out your left with options not otherwise possible. The same goes for the mutli brush method with the resistance placed between the brushes.
 Think about now a little bit of complexity.If you have a portion of output being used to run the device it will be at the voltage it is designed to put out say at 120volt ac but at maybe 1 amp(the portion). You have to figure out how to regulate or limit the portion to that amount without wasting a lot of power in the process or ending up with some unstable form of regulation.
  Like everything ells there a number of ways to do it.
  Some of the early brush designs used layered brushes, alternating between insulating layer and conductive layers in a single brush. Some books state it was purely for strength and longevity but I personally doubt that was the only reason taking into consideration the materials used. There is no way to stress enough that the total real resistances in the device have to be less then the total resistance in the load placed on it at any given instance of time.

 Imagine that.


  Sorry, you stepped into it.lol

Question??

 Now what of this crazy thing. How could you utilize it as it is drawn?

 It may be assumed that all these lines connected the two together actually exist all at the same time. Not so, the represent positions to connect to that move current a little more or a little less to either the N coil or the S coil. Why ever would you want to do that?
  Could it be that if you were drawing a portion from the alternating current and converting it to direct that in that case you will unbalance the wave form of the alternating current?
   If that is the case, which it is.That should lead to you to figure out how he is rectifying the output so as to limit the alternating current being used to excite the inducers that came off the output before it enters at the same inputs as did the battery which started it. Another clue is the current from the battery will be equal to the current from the part or method to rectify the output.

 How do you adjust the current going to the inducers to re balance or compinsate for the rectified feed being used to replace the battery as a source? Both the working load and the power back in dc are off the output.

  You picture of the truck with the magnet pulling itself? How much $$$ do you want to spend to make one?

These images I like. Heh je je je

I have found a reference to the induced coil orientation in the Buforn´s patent No. 47706 (year 1910), the first of the 5 patents that Buforn filed copying Figuera´s 1908 patent. It is the only reference to the induced coil placement I could find in those patents.


"Our invention is also based on that other reasoning "If several spirals or loops are placed within a magnetic field in the plane of the magnetic meridian, from the time they start to rotate a current with weak voltage will appear, and those voltages will add up when the loops are placed one after the other."

Note that Buforn is referering to "the plane of the magnetic meridian". I suppose that the meridian is the line which joins both poles (as the geographical meridians join the Earth Poles).

It seems to suggest that the induce coil is placed perpendiculary to the electromagnets.

Could it be possible? What do you think of this?

Hanon,

Look at this for some info.
Not just earths field but any magnetic field.
