Just got this yesterday from a long time collector, he hasn't run it in 30 years. I put power to it for just a split second to make sure it ran and didn't get damaged in shipping. I was on eggshells waiting for it! The last high-end fan I got, even though well packed, came with a bent shaft. Nice original lolipop, that was a dis-appointment!

Anyway, I was told this fan is from 1899, anyone care to comment? I will post some more pictures when it is assembled.

Very nice Richard , Good Choice. My Favorite because of its simplicity, and they run sooo smooth . I have 2 ,  One of them is complete and running great , the other needs a blade and cage , have the oilers and struts. Darryl just re-shafted the rotor and placed in new bearings , so it's still a project.

Tesla details and motor tags-
From Rob Duffy but not confirmed by me other than by a phone call.   I agree on this:
1896: First cast tag, no screws or acorn nuts on the back of the motor
1897: Cast tag, screws on the back of the motor
1898: Possible first stamped tag or last year of the cast tag and larger motor openings (With brass ring at top of the base)?  No scalloped motor openings, evenly spaced rotor poles
1899-1900: First year for scalloped openings, evenly spaced rotor poles.  A models
1901-1902: Scalloped openings, paired rotor poles.  B models

Between 1896 and 1897 a five strut was made, as well as 1898-1900 (I question these later dates)



That's a good looking Tesla Richard.   I can't tell you much on running it on 60 cycles but Alan Willms, who I got this Interior Conduit AC fan from, said it is fine to do.  I forget if the voltage has to be lessened which I think is true and I probably started it out around 50 volts making sure it sounded like it was running a correct speed. This fan is 125-133 cycles and I have run it for at least an hour with the motor staying cool.

I’d date the Tesla at 1901. I think the A’s were made in 01, and the B’s in 02. The Pancake came in 03.

Nice fan. Seller is a great guy to work with as well. Search the forum, pretty sure people have sussed out how to run a 133 Cycle Tesla on 60 cycles. something about wiring.

I find it interesting that they stamped the “alts” on the blade hub.  I wonder if the pitch is different depending on the stator design? 

I never noticed that stamp on mine.

I can't find an image of a Westinghouse(Tesla) dual speed desk fan motor in 02 electrical trade to save my life. For that matter, I can't find an image of a Westinghouse desk fan in 02 electrical trade, period. Makes you wonder what Westinghouse was up to in their fan motor department in 02.

:clap:Congratulations Richard!! What a beautiful and desirable fan.
I will be watching with great interest to how you run with 133 cycles.  I plugged my 133 cycle it runs slow on one speed. I did not run it long. I was thinking of getting a box that is programmable. I am still in the process of completing it. :clap: :clap: :clap: :clap: :clap: :clap: :clap: :clap:

A Tesla wired for 133 cycles will run fine on slow speed. Teslas had no speed coil. The switch takes it from serial to parallel. On low speed it’s parallel. I sold one to a friend. He ran it 24 hours a day for ten years. So, try it on slow speed.

Those are nice running fans, lucky you.  :D  The facts are is we know for fact what they looked like in 1896. After 1896 they kept using the same d amn images in electrical trade through 1901. The 1897 Westinghouse catalogue uses the same dual speed desk fan images used in 1896 when introduced.  It is kind of hard to talk like you know what your talking about when you have nothing concrete to stand on to talk about. I hope this makes sense.  :D

1898.





1899.






1900.






1901.










No images or mention for Westinghouse desk fan motors in 1902 in available electrical trade to the best of my knowledge. 






Electrical trade mentions minor changes in the dual speed AC Tesla fan motor during its manufacture time period, but nothing specific I am aware of. To the best of my knowledge posting specifics of changes made on this desk fan 96-01 is purely speculation. If someone can share some dated images or documentation of changes made on this fan, have at it.

Testing the Tesla. Put my Kill-A-Watt on a Variac, set it to 100 volts. fan started up on low speed with no problem, about 1.5 amps, settled quickly to 1 amp and has been running smooth and cool at one amp for a half hour. I tried it for just a second on high, jumped up to 4 amps, so I quickly put her back on low, smooth nearly silent at 1 amp.
