That's what some hard-disk manufacturers used for spindle motor drive.

Maybe you could get some useful info from old HDD service manuals - the older the better, the early drives used MSI-TTL to generate the 3-phase, in later models it was all done in firmware on one of several CPUs.

AFAICR; Nidec was one of the most commonly used spindle motors.
