I have a western electric 7901 (R&M) fan I purchased several months ago. It runs real smooth,however the base gets very HOT. Could it be the resistor in the base ? If so, is there an aftermarket resistor that I could use ? Thanks!

It's a Direct Current fan.  It gets hottest on low but less on medium and none on high.   

 

[James Byerly]

Thanks Anthony ! Just not use to a fan component getting so hot . 

[Anthony Lindsey]

On low the switch generates heat from the power it's restricting from going to the motor.  Less on medium and none on high.   There's a better way to explain that probably. 

[Anthony Lindsey]

Are you running that on standard AC power?

[James Byerly]

Right ! I’m on 120 volts A/C .

That's a no no. You need as full wave bridge rectifier to convert AC to DC in route to your switch? Anthony will help you with his big brain. 

[Anthony Lindsey]

Well,  your not supposed to.  Some fans will run and some don't 

Send me your address and I will send you a small bridge rectifier "extension cord" to plug the fan into. 

[Anthony Lindsey]

 BIg brain?   I know there is a joke in there somewhere. 

[James Byerly]

Thanks Guys ! Hey Anthony ,Just let me know the price of the cord and I can  pay you for it. My address: 700 west 74th street  Kansas City, Mo 64114. Thank-you. 

[Anthony Lindsey]

No worries  don't worry about it.    Plug fan into it and it into wall.

[Anthony Lindsey]

And don't run it on AC.

[James Byerly]

Thank you Anthony ! I really appreciate it !

That is an R&M stamped fan

[James Byerly]

Its got a R&M badge on fan guard and western Electric name on motor tag . Would that have been original to this fan . Thanks

[Anthony Lindsey]

It should have an Western Electric badge.

I have a nice one if your interested.   2 1/8" wide.

Those fans were meant to be run on 110 volts, I use a VARIAC at 90 volts or less
