The motor model parameters are complete, no longer afraid to understand the model.
The motor model is a code number that is used in the convenience of use, design, manufacturing, etc. for business contact and simplification of product names, specifications, types, etc. in technical documents. The following is a description of the meaning of the motor model.
First, the motor model composition and meaning
It consists of four sub-sections: motor type code, motor characteristic code, design serial number and excitation mode code.
1. The type code is a Chinese phonetic alphabet used to characterize various types of motors.
For example: asynchronous motor Y synchronous motor T
Synchronous generator TF DC motor Z
DC generator ZF
2. The feature code is to characterize the performance, structure or use of the motor, and is also represented by the Chinese phonetic alphabet.
For example: Explosion-proof type B means YT on the YB axis flow fan
Electromagnetic brake type YEJ frequency control type YVP
YZD for variable pole multi-speed YD cranes.
3. Design serial number refers to the order of motor product design, expressed in Arabic numerals. For the first design of the product, the design serial number is not marked, and the products derived from the series product are marked in the order of design. For example: Y2YB2
4. The excitation mode codes are respectively represented by letters, S represents the third harmonic, J represents the thyristor, and X represents the complex excitation.
Such as: Y2--160M1–8
Y: model, indicating asynchronous motor;
2: design serial number, "2" indicates the product of the improved design on the first basis;
160: the center height is the height from the center of the shaft to the plane of the base;
M1: frame length specification, M is medium, where the footnote "2" is the second specification of the M-type core, and the "2" type is longer than the "1" type core.
8: The number of poles, "8" refers to the 8-pole motor.
Such as: Y630-10/1180
Y represents an asynchronous motor;
630 represents power 630KW;
10 pole, stator core outer diameter 1180MM.
