This is a variation of one of the motors I built. For a simple monopole it would increase the torque significantly by using flux which is normally wasted. Here is the set up:
The diagram on the left is your standard monopole configuration. The magnet is first attracted to the core then pushed away by the coil. The flux for both the magnet and the coil are forced in opposite directions due to their being the same polarity.
The diagram on the right includes a piece of steel right after the magnet. Now, instead of being wasted, the flux polarizes and attracts the steel into the pole. It then becomes a push/pull arrangement.
Of course, as soon as the coil turns off, the steel is no longer attracted to the coil core and continues on its merry way.
This configuration will add torque to any monopole. However, it will probably not add to the top speed (might even reduce it). Top speed has nothing to do with torque anyway. Torque is all about doing work.
If you want to drive a generator coil, fan blade or any other load, this would be a good addition.
If you're just using your rig to charge batteries it might not be worth the trouble. Either way it's something different to try if you want.
Cheers,

BTW, I have not tried this with an SG type trigger (from a bifiler coil). It should be ok but I don't know for sure. Some feedback on this would be helpful.
