there are a bunch of ways to do this, as long as they are done correctly all of them work and as far as I am concerned if it works and is safe, I just don't care much.

people like to whine about how hard it is to replace a motor that has been wired up with bolts and taped over. so what? it is not like you do it on any regular basis. most motors will outlast most electricians.
What about blue wire nuts? :p
I've seen some real motor disasters that have been caused by people using wire nuts on large motors. Small ones, ok (although against my personal code of conduct), but once you have to go blue, you have to stop yourself.

I am not a huge fan of wire nuts on things that vibrate a lot. but, if they are taped over they won't come loose.
