    The goal is for transform motorcycle alternator to 3 phase electric starter motor

    Can anyone help me to create 3 phase driver circuit from 12 volt battery power source.
    - And the alternator rewinding plan is use six from 12 pole. Like attached picture.

    Is this just for academic reasons?
    There is a multitude of series wound DC motors out there for winches etc.

    No.. it's not for academic reasons.. it just for hobbies. i want apply this plan to give my 1975 old Honda Cub motorcycle electric starter. Before i ask on this forum i been googling for 3 phase motor driver circuit but i cannot found circuit for 12 volt input source. and the other reason i like to learn to build driver for 3 phase motor driver. And before i use the circuit on that alternator, my plan is using that on hard disk motor.

    The one you show appears to be on the outrunner principle? Where the wound stator is inside the P.M. field rotor, The RC community use these on a smaller scale, you may glean info from one of those sites for a driver.
    Many of the latest washing machine use these 3 ph motors also.
