And here is an interesting quote from Garry.
Hi Folks, This motor took a long time to make, but was from the design point, made in such a way that I would be able to try as many possible configurations in it as I thought possible at the time and so it has served as a very good test bed for a very long time for me. The very first thing about this is it uses both ends of the "coil" and does not waste one end as many motors do, this also brings in a factor of compression on the electro flux field between the magnets rather than the deflection and thus reduction of efficiency in a single rotor design. Further this causes the magnets by sheer proximity to have their flux fields extend into the coils and thus change the centre of the magnet pair also causing recompression on the coil flux field.
When the coil is powered the flux field of the magnets is no longer attracted to the opposite magnet and instantly with the aid of the building electro flux field pushing it, returns to its normal position and thus the flux field is moving away from the coil while the magnet is approaching. ( The centre of the magnet flux field moves from between the coils to between the coil and the magnet, to do this it is going out of the coil as the magnet approaches.) Add to this that the magnet is only 1mm away from the coil which is 2 mm and there is an air gap which while only 4.5 mm now has been up to 9mm between the coils and you can see that the magnet flux field is in fact travelling backwards in the coil for a long period of time, relatively speaking. Inductive Lenz is removed in this setup and power on Lenz is equally reduced by the fact that each magnet is permeating both coils which as we all now know causes counter current and while the counter current isn't adequate to totally remove power on Lenz, by reducing it, more power get to be converted to shaft output. Lenz in a motor is actually desirable in some respects, its direct effect on the motor is to, minus losses to windage and friction, output a power level that eventually matches the input power and stops the motor from drawing high amps and running away until it explodes from excess centrifugal force. By reducing the Lenz during the driving pulse we move the unloaded speed of the motor higher per volt and again we all know that higher speed from the same input voltage actually results in more horse power. but in this case there is not more current flowing for this higher speed but exactly the same current flowing as if the motor had full Lenz but only went a fraction of the speed. I'm not sure I have accurately described any of this but just look at the hidden actions and reactions and see how they make it better, even if you cant get OU from this you will sure get a lesson or 2 on motors and their internal workings and this cant help but better arm you in your pursuit of bigger and better things.
