More questions about an office shredder than you might expect :) Answered
EDIT: I ruined it so I will not be fixing it. But I'm sure this gets typed into Google a lot so if you reply it will help others...
I recently received one of those big (ish) office paper shredders from a company of a relative of mine to take apart (they know me... :) because it wasn't working like it was supposed to.
After having the idea of fixing and selling it, I read online and figured out that the shredder had never been oiled, so I did that.
But the shredder (motor) keeps heating up, like A TON compared to the 12-15 sheets it's supposed to handle. I can shred maybe 4 sheets at a time maybe 20 in total before it shuts down in the middle of the operation. I think this might be for overheating protection.
Does anyone know what would make the motor heat up so much? Maybe paper dust got into the motor/bearings and makes it work extra hard? And it's not like I can turn it by hand because of these gears. I think it's a brushless motor but it's hard to tell because it's very compact inside.
I do know that after it had shut down, I stopped working on it for other reasons, but after two whole hours I came back to work on it and was shocked to find out the motor was slightly warm!
Anyone know? I can't find any more info on Google. Thanks!
