Induction Motor Standards

Electric motor present from 60% to 80% electricity use in a refinery or chemical plant. Hence, a well design induction motor play a vital role in helping a plant working smoothly and efficiently. In order to guide the select and making, IEC and NEMA has issued series of standards. These standards cover performance, construction, efficiency of motor.

List of codes and standards for induction motor (not exhausted) is as below:
