So when i first got this fan at a thrift store for a dollar it was locked up i got it spinning and then spray painted it and it worked after that but i took the motor off of the box fan and then loosened up the motor to get it out of the motor case with some wd40 so i wasn't able and put it back together then it made a loud humming noise and did not spin at all and was very hard to turn when it was on but when it is off it turns freely so i tuck the whole motor apart and was successful this time to take it apart and put it back together just to see that i sparked and hums louder then before  :hammer:Motor taken apart and the electric tape is so it does not short

This is what it looks like but is not reversible and has red instead of green

I had a GE 3 speed Electrically Reversable Box Fan from the early 1960s that had a motor very similar to yours in it and mine I was trying to take it apart to lube it as the motor was having a hard time getting up to speed and staying there so I took the fan apart and lubed the fan up and then attempted to put the motor back together but when I had the motor reassembled it wouldn't spin when the motor was on or off and the back motor housing cover that covered the bearing housing wouldn't go back on like it was supposed to so I had to scrap the fan out which wasn't too bad considering I picked it out of the trash more or less, and I was able to get a couple of months worth of use out of the unit before it died, but I'm afraid that the way you are describing what your fan's motor is doing that your fan is shot, like mine was, which is too bad because it looked like a nice fan that was from the mid to late 1950s.

Most often, if the motor is free with power off, but locks when energized - there is something loose in the motor, causing the rotor to magnetically be pulled against another part. The picture is small and not detailed so it's hard to see if there are any rub marks or other tell-tale signs.

SETH FROM LOOKING AT THE PHOTOS IT WOULD APPEAR THAT DISSASSEMBLY OF THE MOTOR WAS DONE THE HARD WAY AND NOW THE ROTOR IS MIS ALIGNED ON THE SHAFT AND IT ISNT IN THE RIGHT SPOT TO MATCH THE STATOR. THE FINNED ARRANGEMENT ON THE SHAFT IS NOT SUPPOSED TO COME OFF THE SHAFT IT IS HELD ON WITH AN ADHESIVE OF SOME SORT. BEING THAT IT HAS BEEN REMOVED IT WOULD APPEAR IT ISNT LINED UP RIGHT WITH THE STATOR GOING BACK ON. ....THE CORRECT WAY TO TO TAKE ONE OF THESE MOTORS APART IS TO REMOVE THE MOTOR FROM THE FRAME. ON THE BACK IS A SEALED ROUND CAP THAT COVERS THE REAR OF THE SHAFT AND THE OIL WICKS. IT IS HELD ON WITH AN ADHESIVE. YOU HAVE TO REMOVE THAT CAP, THEN UNDERNEATH THE REAR OF THE SHAFT HAS A GROOVE AND A C-CLIP. YOU REMOVE THE C CLIP AND THE WHOLE SHAFT AND THE FINNED ROTOR SLIDES OUT AS ONE UNIT. ..........MANY OF THESE MOTORS WENT TO THE JUNKER BECAUSE THE FAN FELL OVER AND THE FINNED ROTOR MOVED ON THE SHAFT . THERE WERE SPACERS AT THE REAR OF THE FINNED ROTOR ON THE SHAFT THAT KEPT IT LINED UP WITH STATOR SO THE ELECTRICAL FIELDS MATCHED. YOU HAVE TO TRY TO GET THE FINNED ROTOR BACK ON THE SHAFT IN THE RIGHT PLACE. IF THE SPACERS ARE MISSING OFF THE SHAFT THE FINNED ROTOR COULD ACTUALLY BE LOCKING UP TO THE BEARING TOO . IF THE FINNED ROTOR ISNT ADHERED TO THE SHAFT IT IS JUST SPINNING NOW AND NOTHING IS TURNING THE SHAFT AND BLADE. THERE ARE A COUPLE OF POSSIBILITIES HERE AS TO WHY IT ISNT WORKING...TOM
