Mitre Saw motor issue

[OM99]

Hopefully someone might be able to help.

the motor on my mitre saw suddenly started to make big spark and flapping noise when running, i replaced the brushes in case it was the cause of the issue but to no avail, spark are still there and the noise too.

I dismantled the motor and can not see anything that could cause this issue?

Would the sparks cause be the commutator being worn out and shorting. The spark are also melting a rubber wheel bearing casing

If this is the case? is repair worth it or might as well get a new mitre saw?

thanks

Oli

Depends on age and condition. If its only a couple years old and good condition, repair it. I suspect you would need a new armature.
If it is 20 years old and looks 30, buy a new one.

its about 15 years old, mostly used for diy still looks ok though, its a Rexon M2500a and until now was very happy with it.

Looks an upgrade is in order then, been looking at this one

some decent reviews on amazon for it, seems to be getting a lot of saw for the money.

For that money its no contest. Just finding parts will be a pain.
