If both ways provide the same holding torque, then what would be the negatives of using series over parallel to reduce the current per phase which would also reduce heat in the driver?

I am assuming that since the rated voltage and phase resistance increases the heat produced by the motor would also increase. Is there any negative effect to the inductance increase in series hookup? Any other negatives?

I'd expect that the higher inductance would require a higher peak voltage (as in a constant current driver) to retain the maximum stepping speed.
With a constant voltage driver I'd choose the paralell configuration if high speed was important.
