    Default The old debate of motor vs. engine.

    A friend of mine got into a discussion about motor vs. engine. He seems to think the two are interchangeable while I do believe there is a fundamental difference.

    It's similar to the clips vs. magazines debate for firearms owners.

    I use motor to describe electric devices (blower motor, windshield wiper motor, window motor) and engine to describe what's under the hood powering the vehicle.

    Engines convert fuel via internal combustion to work to move the vehicle. Motors use electric current as the energy source to do work.

    Hybrid vehicles have an electric motor and an internal combustion engine.

    Any thoughts.

    I call them a motorcycle as well, I just refer to the engine part as an engine.

    When referring to boats I call it an outboard engine.

    Ther term motorcycle, motorcar, motorbike are all VERY old terms, only the motorcycle term is still commonly used.

    Without digging out a bunch of old text books, if I remember correctly, an engine uses fuel to create energy which is converted into mechanical work, while a motor converts external energy into mechanical work.

    Therefore, the big block of metal, under the hood, would be an engine; while, as stchman suggested, the blower is a motor.

    electic - motor, uses magnetic pulses to generate energy
    combustion - engine, uses controlled explosion to generate energy
    steam - engine, uses expansion of water/oxegen to generate energy.

    I really think the diff is how the energy is captured... Just my two cents

    I believe you guys are correct... One uses a fuel source to generate energy and the other uses energy generated from another source.

    A compressor requires one of two things to make it work, same with a pump:

    1. An electric motor
    2. An engine (usually a small gasoline engine)

    One of these devices will drive the compressor or pump.
