The motor model parameters are complete, no longer afraid to understand the model!

Second, the specification code

It is mainly expressed by the center height, the length of the base, the length of the core, and the number of poles.

1. Center height refers to the height from the motor shaft center to the bottom corner of the base; according to the height of the center, the motor can be divided into four types: large, medium, small and miniature.

H is a micromotor in the range of 45mm~71mm;

H is a small motor from 80mm to 315mm;

H is a medium-sized motor at 355mm~630mm;

H is a large motor at 630 mm or more.

2. The length of the base is indicated by international common letters:

S—short base

M-center stand

L—long stand

3. The length of the core is expressed by the Arabic numerals 1, 2, 3, 4... from long to short.

4, the pole number is divided into 2 poles, 4 poles, 6 poles, 8 poles and so on.

Third, the special environment code

Special environment code:

"High" original G

Ship ("sea") with H

Household "outside" with W

Chemical anti-corruption with F

Tropical T

Wet tropical with TH

Dry tropical TA

Fourth, the supplementary code

Applicable only to motors with supplementary requirements. For example, the motor code of the model number YB2-132S-4H means:

Y: product type code, indicating asynchronous motor;

B: Product feature code, indicating explosion-proof type;

2: Product design serial number, indicating the second design;

132: The center of the motor is high, indicating that the distance from the axis to the ground is 132 mm;

S: the length of the motor base, expressed as a short base;

4: the number of poles, indicating a 4-pole motor;

H: Special environmental code, indicating the marine motor.

Through the above detailed description of the motor model, I believe that after seeing the product model, you can know the type, characteristics, design serial number, motor specifications and environment used by the motor.
