Motor model number is a code that facilitates the use, design, manufacture and other departments to carry out business contacts and simplify the description of product name, specification, type and so on in the technical documents. The following is an introduction to the motor model meaning and other information.
First, the motor model composition and meaning
By the motor type code, motor characteristics code, design serial number and excitation mode code and so on four subsections of the order of the composition.
1, type code is characterized by various types of motor and the use of hanyu pinyin letters.
For example: asynchronous motor Y synchronous motor T
Synchronous motor TF Synchronous generator TF DC motor Z
DC generator ZF
2, the characteristics of the code is to characterize the performance, structure or use of the motor, also using Hanyu Pinyin letters.
For example: B for explosion-proof type, YB for axial flow fan, YT for electromagnetic brake type, YEJ for variable flow fan.
Electromagnetic brake YEJ Variable frequency speed control YVP
YEJ Variable frequency speed control YVP Variable pole multi-speed YD Crane with YZD and so on.
3, the design number refers to the order of motor product design, expressed in Arabic numerals. For the first design of the product is not labeled design serial number, the series of products derived from the design of the product in accordance with the order of labeling. For example: Y2 YB2
4, the excitation mode code is expressed in letters, S represents the third harmonic, J represents the thyristor, X represents the phase complex excitation.
For example: Y2 - 160 M1 - 8
Y: model, that is, asynchronous motor.
2: design serial number, “2” means the first time on the basis of improved design of the product.
160: center height, is the height from the center of the shaft to the plane of the seat; M1: seat length specifications, “2” means the first improved design based on the product; M1 - 8
M1: the length of the seat specifications, M is a medium-sized, 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 8-pole motor.
For example: Y 630-10 /1180
Y means asynchronous motor.
630 means power 630KW.
10 poles, stator core outer diameter 1180MM.
Second, the specification code mainly with the center height, seat length, core length, the number of poles to indicate that
1, the center height refers to the height of the motor axis to the bottom corner of the seat surface; according to the center of the different heights can be divided into large, medium, small and miniature motors, the center of the high
H in 45mm ~ 71mm belongs to the miniature motor; H in 80mm ~ 315mm.
H in the 80mm ~ 315mm belongs to the small motor; H in the 355mm ~ 630mm belongs to the small motor.
H in 355mm ~ 630mm belongs to the medium-sized motor; H in 630mm or more belongs to the large motor; H in 630mm or more belongs to the large motor.
H above 630mm belongs to large motors.
2, the length of the seat with the international common letters: S -- short seat
M--Middle seat
L--Long seat
3, the length of the core with the Arabic numerals 1, 2, 3, 4,, from long to short respectively.
4、The number of poles is divided into 2 poles, 4 poles, 6 poles, 8 poles and so on.
Third, the special environment code has the following provisions:
Special environment code
The original “high” with G
Ship (“sea”) with H
W for “outdoor”.
F for chemical protection against corrosion
T for Tropical
TH for Humid Tropics
TA for dry tropics
Supplementary codes are only applicable to motors with supplementary requirements.
For example: the meaning of each code for the motor with the model number YB2-132S-4 H is:
Y: Product type code, indicating asynchronous motor.
B: Product characteristic code, indicating flameproof type; 2: Product design serial number, indicating asynchronous motor; 3: Product design serial number, indicating asynchronous motor
2: Product design serial number, indicating the second design.
132: motor center height, indicating that the distance from the center of the shaft to the ground is 132 mm; S: motor base length, indicating that the distance from the center of the motor to the ground is 132 mm; and
S: Motor base length, indicates short base; 4: Number of poles, indicates 4-pole.
4: Number of poles, for 4-pole motors; H: Special environment designation, for shipboard motors.
H: Special environment designation, indicating marine motors.
Through the above detailed introduction to the motor model, I believe we can see the product model in the future, we can know the type of the motor, characteristics, design serial number, motor specifications and the environment in which it is used and other information!
