Hey rod, if you are having a hard time getting the coils to speed up together, try this...
I assume they accelerate at different speeds individually?
If they do, and if the acceleration has to do with core delay, try using biasing magnets on them one by one and work it out so they all speed up at the same RPM. That way you can simply get the rotor up to speed and accelerate all of them at once.
I suspect you would have to "prime" the cores that require the highest RPM (the cores requiring the highest rpm for speedup may/should/could require a slower rpm if you use a biasing magnet. Of course it could be opposite of this, but this is what makes sense to me. Oh, ps, this assumes you will position the biasing magnet so it is in attraction to the rotor magnet as it passes by.
As far as my angled pull idea, just study each magnet on that picture I posted and ask yourself what the magnet would be trying to do (where would it be attracting to the most, what direction?)
