I've actually been chewing on that myself, main problem is retrofitting hall effects or some other position encoder so you can have nice startup torque. The field draw doesn't look to horrible and may provide for better dynamic range, like sepex does. Also I'm not sure what effect the angled field interface on the rotor will have or the overlapping coils in the stator. Those might be there for smooth power, at efficiencies sake.
