Hello, I’m admittedly new to vintage fans but wanted a powerful, quality fan for my shop.  Today I found a locally listed Mobilaire pedestal fan that seemed just what I was looking for.  It’s a 3 blade, hexagonal motor version.  Has the toggle up/down switch in the rear.  Seller swore the fan worked great, but since he wanted to meet in a gas station parking lot, I had to take him at his word.  Paid $125.  Once home, I plugged it in, flipped the switch and it began with to spin but slowly and with a hum.  Tried the high speed and immediately received a pop with a flash of flame!  Took the motor out and drive it to a local motor shop, he said forget it and eat your $125.  Seller won’t give me a dime back.  Searched the internet and found that if these motors aren’t oiled and get dirty, this is the result.  Found one guy who rewound his hex motor and was successful but that’s beyond my experience and I can’t justify the time to muddle through that.  Can’t find any used, original motors either.  So now I’m turning to trying to repower this fan with a modern motor.  Has this been done?  May be sacrilege, I’d hate to do it but preferable to junking the whole fan and kissing the $125 totally goodbye.   
These are oddly sized motors it seems.  4.6” hex width (flat to flat), 4 amp, 3/8” diameter shaft... maybe 1075 rpm?  

Any thoughts or solutions?  Thanks!

A local antique shop near me had one of those fans in their shop running that someone at some point in time had installed a standard air circulator motor inside it and was running it with a vari-speed solid state fan control attached to it on the back.

That really sucks! This is one reason I have a 3KW sine-wave inverter which I take with me for testing anything like this. Extremely fishy when seller insists on meeting at a location where he is assured you won't be able to test it.

To answer your question, yes they can be re powered.  I have 2 with replacement motors. Might have to modify how it's mounted, but it can be done.  Hvac blower motors seem to work out pretty good.  Good luck.  Keep us posted and show us pictures!
