Isn't this actually a repulsion induction type motor? I only see 2 wires to the motor it self. My Century S3 model 15 from 1914 no 65689 has a "phase" winding which I think actually qualifies as a 2 phase motor. The phase winding is delayed through the speed selector choke.
This is a true split-phase motor with squirrel cage rotor and centrifugal switch to disconnect the start windings. My early S3 serial# 6762 also has the split phase motor. The later models, starting with the S3 model 14, went over to the 2-phase system, and those motors will not work without the speed coil.
I do have several Century repulsion-start induction motors, and the rotary governor works the same way as that in this fan.

I had no idea those old fans could run so fast! Awesome piece of equipment

Very nice! I love the open motor design.
