Century S4 Stationary Fan

Several of you asked me to redo the S4 video, as the original was too short.
We recently installed a new headwire and power cord to this fan. It is the earliest serial numbered Century desk fan known, serial# 369. Split phase motor, 5 speeds and a daily driver, this machine will run for weeks without the motor getting warm at all. These 4-blade skeletal motor fans were not meant to be used in a home, but rather, in those huge offices that held many desks and people, or in a factory environment.

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.
