What are the common standards for motor manufacturing?
At present the international standards of the motor there are two standard system:
One is the IEC (International Electrotechnical Commission) standards; two are NEMA (American Electrical Manufacturers Association);
China's motor manufacturing industry by the implementation of the GB (national) standards are basically equivalent or equivalent to the use of IEC standards. The so-called equivalent use, that is translated into Chinese without making changes or making little changes to the direct use of the so-called equivalent to the original international standards without changing the original subject conditions, the reorganization of the formation of national standards after the promulgation and implementation.
1, the domestic standard
The domestic motor implementation of the motor standard is divided into national standards (GB), industry standards (JB machinery industry), enterprise standards (Q / NF standard / South defense); [GB / T for the recommended national standards, GB for the mandatory standards ] Commonly used national standards (GB)

2, foreign standards
The motor standards are divided into: International Electrotechnical Commission (IEC), International organization for Standardization (ISO), American Electrical Manufacturers Association (NEMA), American Electric and Institute of Electrical Engineers (IEEE), German Standard (DIN), Canadian Standard (CSA);
Commonly used International Electrotechnical Commission (IEC) standards are:
