Wouldn't a latch allow the best of both worlds?

The series connection has minute advantage over the parallel in holding

the
inductance of a single winding, and the parallel has 1/4th the inductance of
single, so you end up with 1/16th the inductance in parallel, thereby
allowing
the motor to run 16 times faster in parallel.

(At least, it seems like it should work that way as separate coils on the
same
magnetic components.)
