The motor model is a code that is used to facilitate the use, design, manufacture and other departments to conduct business contacts and simplify the description of product names, specifications, types, etc. in technical documents. The following introduces the information of the motor model and the meaning.
First, the motor model composition and meaningIt is composed of four subsections, including motor type code, motor characteristic code, design serial number and excitation mode code.1. The type code is the Chinese pinyin letters used to characterize various types of motors.Asynchronous motor Y Synchronous motor T;Synchronous generator TF DC motor Z;
2. The characteristic code is to characterize the performance, structure or use of the motor, and it is also represented by Chinese pinyin letters.B for explosion-proof type means YT is used on YB axial flow fan;Electromagnetic brake type YEJ variable frequency speed regulation type YVP;Pole-changing multi-speed YD cranes with YZD, etc.3. Design serial number refers to the order of motor product design, which is represented by Arabic numerals. For the products designed for the first time, the design serial number is not marked, and the products derived from the series products are marked in the order of design.4. The excitation mode codes are represented by letters, S represents the third harmonic, J represents the thyristor, and X represents the phase compound excitation.Y: model, indicating asynchronous motor;2: Design serial number, "2" means the product whose design is improved on the basis of the first time;160: Center height, which is the height from the center of the shaft to the plane of the base;M1: The length specification of the frame, M is the medium size, and the footnote "2" is the second specification of the M-type iron core, and the "2" type is longer than the "1" type iron core;8: Number of poles, "8" refers to an 8-pole motor.Y represents asynchronous motor;10 poles, the outer diameter of the stator core is 1180MM.2. The specification code is mainly represented by the center height, the length of the base, the length of the iron core and the number of poles1. The center height refers to the height from the motor axis to the bottom corner of the base; according to the difference in center height, the motor can be divided into four types: large, medium, small and micro, of which the center is high.H in the range of 45mm~71mm is a micro motor;H in the range of 80mm~315mm is a small motor;H in the range of 355mm~630mm is a medium-sized motor;H above 630mm is a large motor.2. The length of the base is represented by international common letters:3. The length of the iron core is represented by Arabic numerals 1, 2, 3, 4, , and from long to short.4. The number of poles is divided into 2 poles, 4 poles, 6 poles, 8 poles, etc.3. The special environment code has the following provisions:F for chemical anti-corrosion4. The supplementary code is only applicable to motors with supplementary requirementsThe meaning of each code of the motor with product model YB2-132S-4 H is:Y: product type code, indicating asynchronous motor;B: Product feature code, indicating flameproof type;2: Product design serial number, indicating the second design;132: The height of the motor center, indicating that the distance from the axis to the ground is 132 mm;S: The length of the motor frame, expressed as a short frame;4: the number of poles, indicating a 4-pole motor;H: Special environment code, indicating marine motor.Through the above detailed introduction to the motor model, I believe that when you see the product model in the future, you can know the type, characteristics, design serial number, specifications of the motor and the environment in which it is used.
