Model LM2000
Manufactured Dec 2013

This summer, I've noticed a faint and constant friction noise when I first startup the mower.  It is also a little slower to get going to full speed, but it cuts perfectly fine still.  I clean the underside after every time I mow and this noise happens even on the first startup with a clean underside.  Could there be some kind of rust build-up inside the motor?  I store the mower in my concrete floor garage and it gets humid in there once in a while.  Unable to find anything on this site or the internet about this.  I've never hit any rocks or large sticks with it so I cannot think of any reason why it would be doing this except debris/rust buildup inside.

I wonder if the blade could be out of balance a little bit. I had a change in sound on my mower and I thought of the blade. Took it off to sharpen it and noticed it was a smidge out of balance. So I sharpened it and made sure it was well balanced before reinstalling it. Took care of that slight change in sound.

Good thought, but I still have the noise when the blade is off.

Ah, not mentioned in your OP. Good to know that. Does sound like possible debris buildup. There is a thread, as I recall, where someone took their mower apart and showed some debris buildup inside. Not recommended to take it apart as it would void your warranty. 
Sounds like a call to customer service is in order.

Oh, I didn't even consider a warranty claim.  I'll call customer service, but I'm not sure how helpful they'll be considering the machine appears to work fine.  I think there may be grass that got up in the vents near the center where the windings are exposed.  I can have the mower running for a half hour or more and I still hear the noise when it starts up.  I'd think after that long, any surface rust inside would've worn off.
Thanks Mike!
