Motor Encyclopedia: through the model to understand the motor

If you have an understanding of the motor, then you can use the model to analyze the parameters of the motor, the model can know what is the motor, the motor of the various parameters of the value is how much. For example models for NCH32-750W-40SMG1. Through this model, I can clearly know this is a lightweight gear reducer motor, horizontally mounted gear deceleration motor shaft size is 32, motor power 750W, 40 ratio voltage is 380V three-phase, brake also, with the standard installation holes. Maybe you will be surprised how can I know the parameters so clearly? In fact, it is not difficult to understand through the study of a turn. Now teach, teach you how to recognize that name and parameters through the model!

Motor model composition and meaning

The motor model is composed of four parts: the motor type code, the motor character code, the design sequence number and the excitation mode code.

1, type code is to express the various types of motor and the use of Chinese phonetic alphabet.

For example: asynchronous motor T, synchronous motor Y, synchronous generator TF, DC motor Z, DC generator ZF

2, the characteristics of the code is that the performance of the motor, structure or use, but also the use of Chinese phonetic alphabet.

Such as vibration proof type expressed in B, Yb axial flow fan with YT, YEJ electromagnetic brake, variable voltage variable frequency type of YVP, multispeed type YD, crane YZD and so on.

3, the design of serial number is the order of the motor product design, using Arabia digital representation. For the first time the design of the product does not mark the design sequence number, the product derived from the product is in the order of the design.

For example: Y2, YB2

4, excitation mode code, respectively, expressed by the letter, S said the three harmonic, J said thyristor, X phase complex excitation.

Such as: Y2-60M1-8

Y: models, said asynchronous motor;

2: design the serial number, "2" indicates that the first time based on the improved design of the product;

160: the center is high, the shaft center to the base level;

M1: Specifications for seat length and M is a medium-sized, which footnote "2" is a second specification of M type core, and "2" type than "1" iron heart.

8: pole number, "8" is the 8 pole motor.

Such as: 10/1180 - Y-630

Y asynchronous motor;

630 represents power 630KW;

10:10 pole, stator core diameter 1180MM.

With the center height, frame length, core length, pole number

1, the central high refers to by the motor shaft to the base bottom surface height, according to the different centers can be motor is divided into large, medium, small and micro four, of which the central high

H in 45mm~71mm belong to the micro motor;

H in 80mm~315mm belong to a small motor;

H in 355mm~630mm belong to the medium motor;

H above 630mm is a large motor.

2, frame length represented by international letters:

S - short frame

M - the machine seat

L - long seat

3, the length of the core with the Arabia number 1, 2, 3, 4...... From long to short respectively.

4, pole number 2 pole, 4 pole, 6 pole, 8 pole, etc..

Special environment code has the following provisions

special environment

"High" original use G

Ship ("sea") with H

Household "out" with W

Chemical anti rot with F

Tropical T

TH of damp heat belt

Dry tropical with TA

Supplementary code is only applicable to motor with supplementary requirements.

For example: the product model for the YB2-132S-4/H motor the meaning of the code:

Y: product type code, said asynchronous motor;

B: product features code, said the explosion type;

2: product design serial number, said the second design;

132: high motor center, said the distance to the ground to the ground is 132 mm;

S: motor frame length, expressed as a short frame;

4: pole number, said 4 pole motor;

H: special environment code, said marine motor.

Through the above types of motor with the introduction, I believe we will see product types, you can know the specifications of the motor types, characteristics, design number, motor and its environment information.
