There are some sprays you can get to help loosen that too. Have you tried WD-40 or anything like that?

WD-40 works good but PB Blaster is the way to go for frozen or rusted parts. Be careful around plastic as it is a catalyst and will melt some types.

You may have to heat the nut with a torch to free it up without doing damage to the armature.

I have heard so much good about PB Blaster over the last year or so. That is what I have setting around as well now.
