Then again.. I suppose you're using something like 5 or 7 magnets on the rotor and you have 6 coil pair positions, anyway a precessional setup.

I think we already talked a bout this, but from what I had seen on my precessional setups, even though getting rid of the big startup magnetic lock, once up to speed there wasn't any gain or difference in speed versus a normal setup. The cogging force is evenly and smoothly distributed thanks to the odd/even setup, but it still causes some drag. But maybe you're doing something different?

cheers,
Mario
