By "adjust the motor" do you mean physically nudging it to keep the belt taut? That's what Dan (and I) took from the wording of your original post.
If you have to do that every day it's not normal. Once my motor is set up right it stays that way for weeks, or until I bump it by mistake! ;-)
It's not unusual for a new drive string to stretch a little from use, but not every day.
A visibly or audibly vibrating motor is not good. I would ask other AS owners if theirs do that. If the table is new, I would report it immediately to the dealer and to AS. You should be covered by the AS warranty and the dealer may have their own refund/exchange policy. The latter may have a short time limit. Don't miss that window if there's any chance you'll need it.
