Motors such as split phase synchronous (Slo-Syn)
use a PM rotor and capacitor phasing to generate the second

    FWIW, my limited experience with the Slo-Syn motors:

1. Relatively oomphy big chunk of magnet for that PM rotor! MANY salient poles, hence the slooow RPM at 60 Hz.

2. They were being used to fine-position several axis on a machine (printing press). OEM used Scott-Tee transformers as well as caps to generate the 90 degree second phase.
