Seems awfully small for a car

Although it does work, there is some shaking and sputtering until it gets rolling. Just not sure if two of my 6384's will be that much different than the first motor.

Engine is a device that converts heat to work. Steam engine, gasoline/petrol engine, diesel engine, etc.

With electricity, the device that converts electricity to work is a motor.

If you're going to be teaching, use correct terminology.

Selected definitions, from among the several variants on the definition of each word:

engine

• {Oxford Languages} 1. a machine with moving parts that converts power into motion.
• {Merriam Webster} 1: a machine for converting any of various forms of energy into mechanical force and motion
• {Britannica} 1 : a machine that changes energy (such as heat from burning fuel) into mechanical motion

(other common definitions are specific to the conversion of heat energy to mechanical energy, or refer to applications in railway equipment, information technology, etc)

motor

• {Oxford Languages} a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts.
• {Merriam Webster}:
  • 1: one that imparts motion
    • specifically : PRIME MOVER
  • 2: any of various power units that develop energy or impart motion: such as
    • a: a small compact engine
    • b: INTERNAL COMBUSTION ENGINE
      • especially : a gasoline engine
    • c: a rotating machine that transforms electrical energy into mechanical energy
• {Collins} The motor in a machine, vehicle, or boat is the part that uses electricity or fuel to produce movement, so that the machine, vehicle, or boat can work.

Wikipedia notes: "An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy.[1][2]"

So an internal combustion engine can be legitimately referred to as an "engine", or a "motor". Motor was very commonly used for internal combustion gasoline and diesel engines for a century or so, but more recent practice is typically to use "engine". Similarly, an electric (or hydraulic, or pneumatic, or steam) motor can be legitimately referred to as an "engine", or a "motor". "Engine" is often seen as the result of using online translation tools, but more typical practice is to use "motor" for electric machines.


These discussions are easier and more clear if people follow the popular convention of using "engine" for fuel-burning engines and "motor" for devices which convert electricity (or fluid flow) to mechanical shaft power, even though other uses of both words are legitimate. So rather than incorrectly telling people they're wrong, we should encourage the most common use.

They may be legit according to librarians and accountants looking in dictionaries, but in engineering practice and in this forum given an engine comes out and a motor goes in, all you're doing is breeding confusion by not enforcing strict terminology in its vernacular....which you seem to do in your last paragraph after spending a thousand words sowing contrarian confusion. What was the point, Brian?
