Input: Question: Is there a semantic difference between engine and motor? In some cases, would the use of one or the other word be technically incorrect? 
Answer: The real difference, is the fact that "motors" run on electricity, while "engines" run on combustion. However, many people interchange the usage of these words: On the rare occasions we encounter one, we refer to a steam locomotive as an engine, the same word that we give to the motive power of an aircraft. But all electrical devices are driven by motors. In Britain at least, one's personal transport is a motor car (with compounds such as motor trade, motor vehicle and motor sport), even though it's always powered by an engine. Small boats may have outboard motors and then are often called motor boats. From a mechanic: So, what is the difference between an engine and a motor? Motors are electric. Electricity powers motors. Engines are powered by come sort of pressure or combustion, ie: steam engines, automobile engines, diesel engines. Pretty simple, really.
