Title: Do we have an engine, or a motor?...
Post by Serowbot on 09/15/13 at 18:25:24

A. a motor is electric,.. an engine burns something...
We have an engine...

B. It's a motorcycle,.. it has a motor...
We have a motor...

C. an engine converts energy into mechanical work...
A motor is a subset of engines that produce motion as the mechanical work.
We have an engine, that is a motor

D. a motor is motive, it converts energy into motion... an engine is a device consisting of multiple parts...
We have both...

I'll go with both, or either...
D.,..is the oldest, and most rooted definition...
:-?...

PS... you can vote for more than one answer...

In the boating world the outboard is called a motor.

In railroading, the diesel locomotive is usually called a "motor." Of course, it has a diesel engine driving a alternator, which in turn drives a motor. The motor actually pulls the train.

Google finds information using a search "engine."

The LS650 has a gasoline engine, but it also has an electric starter motor, so it has both.

Too much for my brain, do we ride a motorcycle or an engingecycle?

It really depends on what dictionary you use and who you talk to.  I was always told that an "engine" specifically referred to a motor that converted thermal energy into mechanical motion, where as a motor was anything that converted any type of energy or motion into another mechanical motion. If you look the terms up in Merriam-Webster, this is the same general idea that you'll see.  If you look them up in the Oxford dictionary, the definitions are reversed.  Cambridge defines an engine as a machine using energy from steam or fuel to produce movement, but then it calls a motor any engine that does work.

Sounds to me like the square/rectangle rule, except that in this case nobody's sure which is which.  :-?

Seems I have only had "military types" complain as to what things must be called. Ship versus boat seems to really piss naval guys off.  

Being as I like cars and have for 40 years.. I do not think that Detroit, saw any difference between motor and engine, so I pretty have gone with that.

That place where the motor is .. is the engine bay.
Detroit is the "motor city".
Fords FE motor is though to be "Ford Engine".

If the big three used them interchangeably.. I am good with doing so.

PS: I guess I do always use the term motor for an electrical driven device- ie its always electric motor. And I always use engine for steam driven. But gas and diesel.. I either.

Dont worry about that bunch,Theyre screwy anyway,,
IN electronics, THEIR electrons flow from  + to -.

Well, terminology can vary from one discipline to another. But, since we are talking about motorcycles, in 1909, Harley Davidson advertised a 7 HP "Motor". Me? As it was explained to me not too long ago by a grizzled guy wearing a black t-shirt and assless chaps, I have a %^&$#@@@ rice burner.
For what it is worth.

Not to be pedantic, but isn't it that feature (or lack thereof) which distinguishes chaps from trousers?

I think you were mistaken, those chaps indeed equipped with an a$$

English - engine
French - moteur
German - motor
Spanish - motor
Italian - motore
Portuguese - motor

A 5x1 score. Nevertheless, in Portuguese, my mother tongue, we use the word engenho (pronounce engenew), signifying mill.

And, electrons actually flow from - to +.  They are negatively charged.

Hey,, dont try to tellme that,, I KNOW,, but  the Navy teaches it  bakkerds!

Electrons flow from - to +. But at least some electrical engineering classes teach "conventional current flow" in which the flow is + to -. You may notice the arrows in schematic drawings of semiconductors (diodes, transistors) point in the direction of conventional current flow. Until electronic devices came into being, beginning with some of Edison's experiments trying to keep light bulbs from blackening as they aged, it didn't matter. Though I don't think he understood what he found at first, he discovered that electrons would "boil" off a hot filament but not from a cold one. Only then did "electron flow" become important.

Engine, for me. An engine turns a fuel into energy, a motor turns one form of energy (yes I know the fuel is a latent form of energy) into another. Engines burns fuel, makes power. Electric motor, takes electrical energy (made somewhere else) and makes power. Steam engine: The whole assembly, burner, boiler, powertrain, is an external combustion engine, but the part that uses steam to make reciprocating and rotary motion is referred to as the motor.
So if the Savage single was converted to run on compressed air, then it's a motor but burning petrol, it's an engine (it's what I learned in Diesel mechanicing school, anyway).

Why is an engine held into the chassis by motor mounts? :o

Haha, it's not. We use engine mounts.

In the utility industry a motor has something connected to it, i.e. power cables, pnuematic lines etc.  An engine can be more portable as in an automobile or motorcycle with the fuel source stored on board.
