Hi
My table fan dropped from the table to the floor last night (because the fan was at full speed and it moved by itself bit by bit during operation). Now the fan won't spin anymore. Upon taking it apart I observed the following:
1. No aparent physical or electrical damage. The winding seems still intact, no distortion of mechanical parts which would have been a result of the drop. In fact, as I know, fans seldom die from drop.
2, The armature, seems to be working. It stil generates a strong magnetic field when turned on without the axle.
3. Without the axle, the motor generates noises as if it was operating normally.
4. When the axle is put in, the noise generated by the motor reduced, and the axle could not rotate, even if attempted manually. In fact, it's very easy to rotate the axle manually when turned off, but once turned on, it's difficult, if not impossible. If the screws are tight, the whole mechanism just sticks together, perhaps because of the magnetic field and moving the axle would move the whole thing. If the screws are not tight, moving the axle would spin it a bit, but does not start the motor as expected
Any ideas what's wrong? Thanks in advance.
