A motor can also be driven by a spring or hydraulics as well as electricity. My guess is that most folks haven't been given the definitions of each and/or don't care. It's kinda like calling a facial tissue a Kleenex(R). I know it's a stretch but I think you get the idea. So among the educated (manufacturers) why do they call it a "motor mount" and not an "engine mount?"

Anyway, I remember my auto shop teacher from high school explaining the difference between motors and engines this way:

A motor takes one form of energy and converts it into another, i.e., electrical energy converted into mechanical energy as in an electrical motor. An "old fashion" watch with springs and gears is another example.

An engine takes a raw material and converts it into energy, i.e., gasoline is burned in an engine to produce mechanical energy.

As we think these deep thoughts; have a great Thanksgiving! I know I have plenty to be thankful for; my family, friends, work, my 'bolt, and more than I can mention here.
