Robert Alexander Motor/Generator

[oouthere]

Just a quick update.  I'm still working the Robert Alexander patent project (Patent # 3,913,004) but with no success thus far. 
In an attempt to use the flicker circuit to reduce back emf I mounted a VW point distributor to the shaft and tried various timing settings using the original draw down resister, this made no difference in the input/output efficiency.
The exciter coils are double wound, four #10 or #8 wraps to about 100 wraps or so of #14 wire.  I isolated the large windings from the smaller ones and tied those to the a/c output (normally DC driven) in an effort to simulate a counter emf effect but this also had no real effect.

Patent #5,892,311 is based on a rotor design that uses the same polarity on each end of the rotor shaft:
  (North- shaft length-South)  Only pulsing the coils on one end with the same polarity.  The idea is to have the coils reversed and the rotor magnets (shoes for electro magnets) making symmetrical rotational balancing  using a four coil set with only two of the coils being pulsed at a time.  All of the current is fed through the non rotor pulsed coil in wired in such a way as to attract the rotor away from the current producing coil.

I don't believe it will work well with this Onan generator (a modified alternator frame is better suited) but the rotor (which is the armature normally for this generator) does have the same pole at both sides if driven by an external dc input.   The problem with the Onan's single polarity rotor idea is the south pole mushrooms out from the center and this interacts with the non-pulsed coils. The worst part of trying this is the need to externally rotate the generator and this is not how the Alexander patent states it works. 
I have a second rotor and but in patent #5,892,311 it shows only enough rotor segments to interact with one full face of an armature coil.  I believe grinding off the unnecessary segments from the rotor may help reduce the mushrooming flux from the unipole rotor, really not looking forward to having to hand wind a rotor that large!

  Just an additional note, physicist Richard Clark used an Onan 1AJ (1KW/four pole/1800 rpm) generator to replicate Robert Alexander's work.  The 1AJ and the LK2.5 are the same generator set-up types.  Patent #4,885,526 talks of the compensation coil and in two of the diagrams it shows a single polarity pulsing of the coils....

Hi all,

After watching carefully Robert Alexander US patent 3,913,004 drawing I have discovered that the correct polarity in the Alexander device is  with like poles facing each other ( N-N !!!). Alexander drew it so that everyone would think that was N-S, but if you interpret correctly his drawing you will note the correct polarity of the magnets. Maybe Alexander was trying to hide this feature.

I attach a corrected sketch below.

Mechanical inverters have been around for some time now,but now the solid state ones have taken over.

Hi all,
You can see more clear in Figure 2 of Alexander patent that poles are oriented with like poles facing each other. The right stator pole orientation is North - North. I can not explain why, but this is a real fact. Figure 1 is the one that everyone knows and that figure 1 is drawn to mislead us.
