In today’s machining and engineering industries, there are two different standards for motors, the National Electrical Manufacturers Association (#NEMA) and the International Electrotechnical Commission (#IEC). For North America, the NEMA guidelines are the standard, and for the rest of the world, the IEC guidelines. Although both organizations offer standardizations for size and dimensions, testing, and efficiency, there do exist some key differences between the two. The most distinct differences have to do with electrical design, mechanical design, and the particular testing methods required by each organization.
