'motor-driven' originates from the combination of 'motor' and 'driven', where 'motor' refers to a machine that supplies motive power and 'driven' means operated or controlled.

'motor-driven' evolved from the increasing use of motors in machinery and vehicles, combining the words 'motor' and 'driven' to describe devices powered by motors.

Initially, it meant 'powered by a motor', and this meaning has largely remained the same in modern usage.
