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