My mini tower desk fan just stopped working. Everything (including interface and the actuator) worked but the motor. When i inspected it (still plugged) it was hot. I unplugged it and let it cool.
Thinking it was the dust building up, i opened it and vacuumed the dust away. I tested it and it still didn't work but it emitted a buzzing sound.
I examined the electric motor and it was really different to what i expected. Connected to the turbine was a cylindrical solid metal horizontally "wrapped" with flat metal which with an attached coil electromagnet in its side. (See this picture: http://www3.jetro.go.jp/cgi/ttppoas/an_dsp.cgi?keyid=1026244&seq=2)
Note: You can slightly see this rotating cylindrical solid metal in the picture.
As i personally tried to rotate the turbine, i felt that it was in need of lubrication. It turned like what it feels to twist a pen cover on a pen. In theory, to make the fan more efficient, resistance among the moving part should be the least.
My question is, is it SAFE to lubricate (using a WD40) the rotating cylindrical solid metal? Or basing on the symptoms, is the motor actually dead?

Re:
No. you are correct in attempting to lubricate this motor, except that use 30W motor oil...WD40 is great to "loosen" the bearing, will only last a short time. The motor shaft should spin freely as this is not a permanent magnet type motor. This motor is widely used and quite common. I often "cure" broken machines by lubricating these motors. There is only a magnetic coupling (when powered) between the rotating shaft and coil. it should be safe to handle this motor even when powered up, providing there is no electrical damage to the coil. Think of this motor as a magnetic machine that requires AC power for the magnet.

Here is what one said:
"To clean it, you will need a small paint brush, screw driver either flat or crossed, then disassemble it. Loosen the screw and just be observant what you put apart. Then clean it. Good"
You may want to take it to a gas station and REALLY clean it out? OR a aerosol canned "AIR DUSTER" will be very useful too!
How to clean your Dyson Cool AM01 or AM06 desk fan, AM02, AM02 Living, AM02 Mini, AM07, AM07 Living or AM07 Mini tower fan, or AM03 or AM08 pedestal fan.

where is the fuse for the remote central locking in a mini one (2001) as I have changed the battery in the key fob and still not working. Can it be reset?. it has 2 button and not 3 on the key fob. Could the problem be a fuse that stops the actuator in the door from working?
Hi, if you can see the drive in Disk Utility, is the volume appear greyed out? If so, then it sounds like the directory has been damaged, which usually is caused by disconnecting a drive improperly or losing power. DiskWarrior is a utility that can often repair a damaged directory and allow the drive to mount.
Hi,try swapping the Memory chip ie putting it on the other slot,also test with another processor if after all these system does display,i'll suggest you go get a new board.
A mini tower is a PC desktop case which is approx half the height of a full size desktop tower case. ATX probably refers to a ATX switch mode power supply.
My chefmate is **** because the internal fan is garbage, its cheap, it
doesn't work or give enough flow, try a higher flow unit. You can get
the 12v at tigerdirect.com with some high flow (AND LIGHTS :) ) for a
few bucks to save your 100 dollar investment. The removal of the orig
fan is easy. The evap is a good setup, but the cooling setup for it
seems to be sh*t. Cheap fans = cheap setup and this is why everyone
hates these units cause it can't pump the goods.
For the record my fan died, so my evap and fan froze over completely
and spoiled my food and burned out the fan completely and probably
helped to short it. I can get it going if I flicker the fan with my
finger but she is dead and can't catch naturally. You could replace the
chefmate fan with most computer fans too... fyi if you got a junk tower
laying around.
While your at it clean the fans on the back and take off the back panel
which kicks out the hot air from the hot flow. It helps if your unit is
older (a year plus+ in a dorm is like 4 in a clean house lol)
