First time dealing with electric motor, please don't make too much fun of me...
(OP)
Hello everyone, I'm a computer engineer and a programmer, so I don't have any experience with large electric motors, please don't make fun of me, and please try to help me with my problem, and help me help you help me with the problem by asking me to any details you may need.
I took up woodturning a couple of years ago, and now the need for a sanding wheel arises, and like any wood worker, I'm trying to make my own.
I had an electric lawn mower which I didn't use anymore, on account of not having a lawn any more, and it was taking space in my work room, so I salvaged the motor to use in my new sanding wheel.
My problem is very simple, if I let the motor run (and it runs just fine), without any load on it (wheel not mounted, and blades of course already taken off), the shaft of the motor gets very hot, so much so that I fear for the wood wheel I've made for it.
Could it be this is normal? the motor itself does not get as hot as the shaft itself but it does get hot (as I would expect). I was thinking some lubrication could be in order, but it has no grease nipple, no indication on the motor to any treatment needed, in fact, the lawn mower was so cheep (it cost me 35 euros 5 years ago, on sale..), the motor has nothing on it at all to help me understand what, if at all, is the problem (again, this could be just normal for this type of motor...).
The only textual reference I have is written in the motor's start capacitor, and I hope this information is helpful:
KAI LU
CCC60 SH
16uF+-5% 50/60Hz
450C ~ C
25/70/21 P0
CE 2009
Should I just spray the whole motor with WD40? should I leave it like it is? any advice would be more then welcome!
(p.s, running on European 220v).
Thanks!

and lets it run for... a half hour for example, you'll find that the shaft is the hottest part of the motor.

Are you running it sideways?
Does the motor turn easily by hand AFTER it is disconnected from the power supply? Be careful of your safety!

This operates magnetically when power is applied.
Its normally at the drive end.
If insufficient load is applied,the brake sometimes doesn't operate as the induced magnetism isn't strong enough.
This will cause a hot shaft.
You would do better just buying a sanding tool,safer and cheaper in the long run.

Sure theode, I could buy a sanding wheel, but building one myself? can't pass on the manhood high from that project, among the wife, the little kids, the job and the bank on my heels, I need something to assert my manhood at... :)
Thanks guys/girls for all the help, and thanks for not smirking at my lack of knowledge, I really appreciate it.
