We were recently asked “What’s the difference between an engine and a motor?” Although it seemed at the time like a simple question, we thought we’d address it quickly here. The following are WordNet definitions:
- A motor is a machine that converts other forms of energy into mechanical energy and so imparts motion.
- An engine is a motor that converts thermal energy to mechanical work.
It’s a matter of semantics. Just as all squares are rectangles, all engines are motors. Granted, an engine is a specific type of motor, one that converts thermal energy, so if there’s no combustion, there’s no engine, but not all motors are engines.
