Fan Motor Lubricant?

I bought a "permanently lubricated" 1/2 HP electric motor that used to be on a large floor fan. When I tested it, it made noise, but did not turn. I opened the casing to find that the lubricant was almost gone, and I'd like to replace it. What kind of lubricant can I use that will last, and where do I put it? Thanks!

If it is a sleeve bearing motor then you may have to take the motor apart to get oil into the bearing wick.
There should be an absorbant packing around the bearingwhere the oil goes.

20 weight NON-DETERGENT motor oil is the proper lubricant.
Do not use regular motor oil as the bearings will gum up.

You will however need to make sure you don't have a ball bearing motor.
If it is then you would need to replace the bearings.

More info:

I will also add that if the motor is hard to turn then there is the possibility that the bearting has worn to the point it will need to be replaced.
Just applying oil may not make it work.
The least you should do would be to dismantle the motor and clean the shaft and inside surface of the bearing to remove any gum or varnish.

If there is any side/side play then the bearings will need to be replaced.
