Noun

A machine, esp. one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device..
This is the common sense in which motor is used today but historically it had perhaps a broader meaning in for example a horse attached to pull a wagon could be called amotor. Before the age of machines it might have been defined asthat which or one who moves something else. Thus for example nerves which send impulses from the central nervous system to peripheral muscles to cause them to move are calledmotornerves.
