Welcome to ECN!
I am unsure exactly what your Question is directed towards, so could you please add some more information?
Basically, the PSC Motor is an excellent candidate for Fan use - especially Axial Blowers ("Propeller" Fans).
These Blowers are normally used for Applications requiring larger volumes of Air at lower pressures (as compared to Centrifugal Blowers / Fans), so high speeds are not necessary.
Additionally, a direct connection may be done to an Axial Fan Blower with the PSC Motor, instead of connecting through belt an pulleys to achieve a low top speed.
Maximum RPMs (highest speed) depends on the number of Poles on the Stator.
I have not seen a 2 Pole PSC Motor (would have Max. high speed of 3600 at no load, slipping down to around 3450 RPMs).
Seen 4 Pole (1800 RPM), 6 Pole (1200 RPM) and 8 Pole (900 RPM) PSC Motors.
I think the typical Ceiling Fan would be a 16 Pole Motor, with a Maximum high speed of 450 RPMs.
These have speed controls via an Auto transformer wound into the Stator assembly.
Looking forward to your reply.
Thank you.
Scott
