Product code: It consists of four sections in sequence: motor type code, motor characteristic code, design serial number, and excitation method code.
1. The type code is a Chinese phonetic alphabet used to represent various types of motors.
for example
Asynchronous motor Y Synchronous motor T
Synchronous generator TF DC motor Z
DC generator ZF
2. The characteristic code is used to characterize the performance, structure, or purpose of the motor, and is also represented by Chinese Pinyin letters.
for example
Explosion proof type is represented by B for YB axial flow fan and YT for YT
Electromagnetic braking YEJ variable frequency speed regulation YVP
YZD for variable pole multi speed YD crane
3. Design number refers to the sequence of motor product design, represented by Arabic numerals. For products designed for the first time, do not label the design number. For products derived from series products, label them in the order of design.
For example: Y2 YB2
4. The excitation mode codes are represented by letters, S represents third harmonic, J represents thyristor, and X represents phase complex excitation.
