The motor model is a code that is convenient for use, design, manufacturing and other departments to carry out business contacts and simplifies the description of product names, specifications, types, etc. in technical documents. Today, the editor will take you to understand the meaning of the motor model and other information.
The model of the motor consists of four parts: motor type code, motor specification code, special environment code and supplementary code. Follow the public account "Hydraulic Shuo" to get more hydraulic knowledge.
It consists of four subsections in sequence, including motor type code, motor feature code, design serial number and excitation mode code.The Chinese Pinyin letters used to characterize various types of motors. For example: asynchronous motor Y, synchronous motor T,Synchronous generator TF, DC motor Z, DC generator ZF.
To characterize the performance, structure or use of the motor, it is represented by Chinese pinyin letters: B for explosion-proof type, YT for YB axial flow fan, YEJ for electromagnetic brake type, YVP for frequency conversion speed regulation type, YD for pole-changing and multi-speed type, crane With YZD etc. Follow the public account "Hydraulic Shuo" to get more hydraulic knowledge.
3. Design serial number
Refers to the order of motor product design, expressed in Arabic numerals. Products designed for the first time are not marked with design serial numbers, and products derived from series products are marked in the order of design, such as: Y2, YB2.Indicated by letters, S represents the third harmonic, J represents the thyristor, and X represents the phase compound excitation.
The specification code of the motor is mainly represented by the center height, base length, iron core length, and number of poles.
1. The center height is the height from the center of the shaft to the base plane. According to the center height, the motors can be divided into four types: large, medium, small and miniature. Among them, the center height:
H in 45mm~71mm belongs to micro motor;
H in 80mm~315mm is a small motor;
H between 355mm~630mm is a medium-sized motor;
H above 630mm is a large motor. Follow the public account "Hydraulic Shuo" to get more hydraulic knowledge.
2. The length of the frame is represented by international letters:
S - short base
M——Middle base
L——Long stand
3. The length of the iron core is represented by Arabic numerals 1, 2, 3, 4, from long to short.
4. The number of poles is divided into 2 poles, 4 poles, 6 poles, 8 poles, etc.
Special environment codes for electric motors
Motor products are often affected by harmful factors in the surrounding environment during storage, transportation and use. According to the nature of the environmental factors, the special environmental conditions of motors can be divided into two categories: natural climate environment and industrial environment: natural climate environment mainly includes tropical, ocean, cold, underground and plateau environments; industrial environment mainly includes corrosive environment, Explosive environment, high and low temperature, high and low pressure, solid particles and dust, high-energy rays and special mechanical loads and other environments.Special environment code: G for "high" original, H for ship ("sea"), W for outdoor "outdoor", F for chemical anti-corrosion, T for tropical zone, TH for humid tropical zone, TA for dry tropical zone.
Supplementary code of the motor
Supplementary codes are only applicable to motors with supplementary requirements, expressed in Chinese pinyin letters (should not be repeated with special environment codes) or Arabic numerals . The content of the supplementary code includes installation method, protection level, etc.
1. Installation form
There are two installation forms : vertical (B) and horizontal (V).
In actual production, B3 (with base, no direct connection mounting flange) and B35 (with base, with direct connection mounting flange) are commonly used for horizontal type, and B5 (vertical type) is commonly used for vertical type. , no base, with direct mounting flange) installation method .
B3 installation
The frame size of the motor is the same as the center height, and the installation size and overall size are the same. Follow the public account "Hydraulic Shuo" to get more hydraulic knowledge.
2. Protection level
The protection level of the motor is divided into the protection level of anti-contact and the protection level of waterproof. IP23 means to prevent the entry of solids larger than 12mm, and to prevent the motor from splashing water: IP44 means to prevent the entry of solids larger than 1mm, and to prevent the motor from splashing water.In summary, when we see that the product model of the motor is YB2-132S-4 H, we understand its meaning:
