While taking a ride through the country side in an attempt to get out of the house, avoid crowds and to see a new antique store, I found this Emerson 5110 Trojan.  It was setting on an outside porch with a bunch of other rusty junk, but had no price tag.  I inquired within and was told that the price tags just get wet and blow away.  I said "OK, but how much"?  It was $18 with discount.  The condition is complete and good except for broken cage wires and nicked blades.  Now soaking in PB Blaster before taking apart.  

THEY ARE STILL OUT THERE, just not as abundant.

Great find. I really like the Trojan pancakes. Paid a lot more than $18 though.

Can anyone tell me what "FOR 7200 ALTS PER MIN" means?  This is stamped on the info tag.

Carlton gave the short answer...

7200  alternations per minute divided by 60 seconds equal 120 alternations per SECOND.

1 cycle consists of 1 positive and 1 negative alternation... TWO excursions from zero volts.

120 divided by two gives you 60 cycles per second.


Great find of the Trojan! 

Did you get the "senior" discount???  :D :D :D

Thanks Carlton.  Thanks John.  I have never seen AC frequency expressed like that.  Was it common in early electricity?  
Well John, the original price had been $20, and I was only given the standard 10% discount.   :cry:

And another fan listed with "Alts", a c.1896 Interior Conduit.That gives a range of 120 to 150 cycles per second which is an unusual frequency range.

Well, I couldn't leave it alone.  Thanks to some donors on the blades and cage, the restoration was finally  completed today.  Runs great and I hope to take it to Harrison for "show and tell" in May.

I have long wondered the same.  Do the "winds" tell us something about frequency or, possibly, how many times the wire is wound around a form?
   Meston motor tag-

It appears from what I see in the books Emerson started to standardize their desk fan motors with the introduction of the 95 back lever induction fan motor. They were advertising 60 and 133 cycle models. From what I have seen the brushed tripod Meston desk fan model introduced in 92, maintained after the 95 introduction back lever induction desk fan was then offered in standardized cycles, with two exclusively offered in 96 being 125 and 133 cycles.(15000-16000 alts.)


I see Meston fan motors with tags that appear offered 93-94 season with what appears to be custom windings for specific frequencies. One example with good fortune stamped 12000 alts., that being 100 cycles. That specific fan motor was 100 VAC with 360 winds. So that specific fan at 50-52 VAC would have roughly 180 winds at 12000 alts. 


This doesn't help much, but, what may help would be to gather as many of these earlier Meston tags known compiled showing volts and specified windings to try and pin point frequencies.
