In short: the International Electrotechnical Commission (IEC) standards are the uniform standards indicating the efficiency classes for electric motors. In 1999, the European Commission established different efficiency classes for electric motors.
What is a NEMA starter?
NEMA electrical motor starters refer to a standardized rating system for the electrical performance of the most common style of American-built motor starters. NEMA starters are rated by size: 00, 0, 1, 2, 3, 4, 5, 6 and 7.

What are IEC materials?
Print materials such as posters, brochures, flyers, billboards, etc. that are intended to draw attention to information about disease or risks to health are often called “information, education, and communication” (IEC) materials.
What is NEMA motor size?
Step motors are categorized by NEMA frame size, such as “size 11” or “size 23″ or “size 34”. Generally speaking, a size 11 step motor means the mounting face of the motor is 1.1 inches square; A size 23 step motor is 2.3 inches square; A size 34 step motor is 3.4 inches square, etc.

What are IEC standards and IEC ratings?
The International Electrotechnical Commission (IEC) is a non-profit, non-governmental international standards organization that prepares and publishes international standards for all electrical, electronic, and rated technologies, which are collectively referred to as “electrotechnical”.
What is IE rating of motor?
Internationally, there is a standard which stipulates the energy efficiency of low voltage AC motors, namely the International Efficiency (IE). The purpose of which is to promote higher energy efficiency to reduce the energy consumption and the energy cost of low voltage AC motors.
