Some second-hand desk
  fans I'd like to find at a
second-hand thrift store.

Darn, I ain't got the extra 2 quarters to splurge on the 1510. Guess I'll have to settle on the EI-2 😕

Patrick, you know that E.I.2
will not run very well plugged
into your home's wall outlets?

If I had an E.I.2,...   I'd sell it. *

 

 

*   And buy a Walmart Lasko
      fan.  At least it'd be able
       to run on house current.

I see it's 133cycles. Guess it's the 5310 for me

Even adjusted for inflation,
I'd be all over the E.I. 2.

It is wound for 104 AC. It will operate safely at a slower speed of roughly 52 VAC. Or I see prices for a variable frequency drive (VFD) online are coming down significantly from the past. 🙂

If a motor is wound for 104v 133hz, are you saying cutting the supplied voltage in half (52v) will subsequently cut the hz in half (66.5), ie close to 60hz coming out of the wall outlet?

Thanks...

Hey Russ, please disregard previous question in lieu of below.

Specifically, how does cutting voltage input in half make it safe to run a 133hz motor on 60hz household power frequency?

The high frequency motor will operate on half intended voltage, but not efficiently. A (V).ariable (F).requency (D).rive will match the intended frequency to operate a high or low frequency fan motor.

BTW....I just posted the electrical trade information copied and pasted in the above post this year not long ago on the forum, and in the past on the old website forum. I have been hoping that someone young in the organization would take interest in fan motor history like I did following Loren Haroldson. The AFCA made a wise move salvaging what was possible from the old website in the provided search feature. It may be all that is left to help members validate fan motor history and finds in the not-too-distant future.

Thanks for posting Russ.

I certainly have an interest in the HOW of things, and enjoy learning as much as I can in response to posts, and am glad that it all gets documented for others to review if helpful now or down the road...
