I have a near mint condition Berns B20 Fan that gave up the ghost this weekend and I am looking for a replacement motor. Either original or aftermarket. I just want the fan to blow again! I am posting some pics including the tag on the motor. I cannot find anything on it! Please help or point me to someone who possibly can.

Sparks and smoke shot out of the windings. I cant figure out how to add multiple pics but will do my best. I would love to have the original motor repaired but will also take a replacement motorAlbum Link: https://photos.app.goo.gl/zUCPYYJEhyz1GnBG7

You might consider getting a FASCO replacement motor.
Size?  3.3 or 5.6"
Shaft diameter and rotation direction.
3 speeds
1050 RPM
Amp draw 2.6 amps @ 115 VAC
Air Over
Shaded pole or PSC.

Good luck, happy fanning!

 I found a motor for sale at grainger that seems to have close to the specs that you have for your fan, I do not know what the shaft diameter was on the original motor was, but the link will have the dimensions of the motor.  Here is the link to the motor: https://www.grainger.com/product/CENTURY-Direct-Drive-Blower-Motor-4MB44 hope this helps.

I have spent so much time looking for the right motor for this. It just does not exist.... The one Ken found was close but the wrong rotation and frame type. Part of the problem is that with the rear mounting and depth I may run in to clearance issues.

you had an original style plain box fan motor and it should be either 3/8 or 1/2" shaft ...most of those westy motors were 1/2". plus most should run clockwise when the shaft is facing you ...i would go for finding a used motor on this site. Charles Tredrick and Mike Mirin come to mind as sources

3 speed box fan motors are fairly common. Maybe you could try something like this? Might be a bit more powerful than what you're used to but at least it would work and it should fit theoretically. You'll just have to cut the shaft off of one side. Also make sure the shaft is the correct size.

I had that exact fan, and the same exact thing happened to me it was running fine one day, then POOF couple sparks, then a small fire. I tossed mine but i wish i would have kept it, they are nicely built fans

I did wind up with that fan motor and it did work! Being that it is a bit bigger, there is not much change between speeds but I am glad to have it back up!
