It's a big 3-speed chinese made fan. It seems that the electricity is going on since I see flashes at the switches. I also hear a light sound. Maybe the motor is dead.

The motor is probably still repairable if you have the patience.
Check to see if the fan blade can turn freely, probably not.
Most likely, something has got wraped around the shaft, and is binding.
The motor naturally gets hot and needs to be cooled.
This happens when the fan turns, cooling it self. The motor will overheat if it is not turning for a while. It has a thermal fuse down inside the motor winding. If it overheats, the fuse opens, and "that's all folks".
Sounds like that fuse is ok, because you hear a humming sound when plugged in, but the blade does not turn.
( unplug it.),
Look to see if some string, or something is wrapped around the shaft. An Exacto-knife might be useful to cut the binding material.
If that's not it, you will need to disassemble the motor, and clean the old dirt and grease from the motor. Usually there is some good clean grease inside the motor, and you can move it to the shaft where it is needed. You can also use a light silicon oil to help free up the shaft.
It will take a bit of work, and it will be a little messy, but the fan should operate after you are finished.
May the force be with you.

Yes u are right motor is dead but also i think the coiling on the motor is also burnt so you might have to change the motor if u want the same fan or else throw it out and get a new one

There are only 4 parts to a fan ,1 the rotateing part of the motor, 2 the stationary part of the motor, 3 the switch, 4 the cord If you can turn the blades easily(with one finger) the rotating(and bearings) part is ok.if it humms then the cord and switch are probably ok(open in stationary winding).Since the winding is the most expensive part,if its open or burnt then throw it away.(the bearings,switch,cord can be replaced.

old model electric fans usually has a good stator motor.(or motor rewinding) problems for these occurs on the shafting and bushing.used for a long period of time the shaft and bushing wears out causing the rotor to be mis-aligned.when this happens, the electric fan cannot be used properly.

austin_semiconductor's answer is correct. However, I would recommend that you think twice about repairing a fan motor. If it stalls it can eventually catch fire (I've seen it myself) and cleaning and lubing the bearings is often just a temporary fix. A cheap fan only costs about $20 new. How much is a burned home worth?

Yeah, go buy a new fan.
