You need to check the motor plate.
It should till the insulation rating.
Typically it is over 100¡ãC or 212¡ãF

How hot? That would be kind of important. They will run warm. If you can lay your hand on it, and keep it there, it's probably not too hot. If you can't, it is too hot. You might try aiming a fan at it, and see if that helps. Also blow the dust and dirt out of it, and check the brushes. if they're worn out, it has to work harder, and that will cause it to heat up more than it should.
HTH!

I have a Harborfrieght Mini Mill and I noticed that the motor and spindle were hot to touch after 25-30 minutes of use in this current warmer summer temperature. My question is, is this a concern? Should I be worried, can it get over heated or is it just normal use? I hope this isn't an extremely dumb question but I just don't want to inadvertently burn out the motor or melt wires. Thank you in advance!?
