National Standard of the People's Republic of China
Method for Compiling Product Models of Motors
Speciflcation for model
of rotating electrical machines This standard applies to the compilation of product models of various types of rotating electrical machines except control motors. 1 Principles for the use and compilation of product models
UDC 621.$13
GB 4831--84
1.1 Product models are codes that are used to facilitate business contacts between departments such as users, manufacturers, and designers and to simplify the description of product names, specifications, types, etc. in technical documents. The basic principles should be simplicity and non-repetition. 1.2 Product models are composed of Chinese phonetic letters approved by the First National People's Congress on February 11, 1958, as well as international common symbols and Arabic numerals.
The selection of Chinese phonetic letters should be based on the following principles:. For Chinese characters with representative meanings in product names, the first letter of their phonetic letters shall be used. b.
If the above letters are repeated in the model or cannot be used due to other difficulties, the first letter of the pinyin of other Chinese characters in the product name can be used.
If there are real difficulties, other letters can be used. c.
1. The product model of various types of motors applicable to this standard must first go through the application procedures before it can be used. The components of the product model and its internal provisions 2.1 The product model consists of four parts: product code, specification code, special environment code and supplementary code, and is arranged in the following order:
1[2-34
Supplementary code
Special environment code
Specification code
Product code
2.2 The product code of the motor consists of four sub-sections: motor type code, motor feature code, design serial number and excitation method code.
2.2.1 The type code is a Chinese phonetic letter used to characterize various types of motors, as specified in Table 1. In the case of a small product nameplate and a long model, if there is no confusion between the numbers and letters of the product code, specification code, special environment code and supplementary code, the dash can be omitted. Issued by the State Bureau of Standards on December 24, 1984
Implementation on May 1, 1985
GB 4831—84
Asynchronous motors (cage type and winding type)
Synchronous motors
Synchronous generators (except steam turbine generators and hydro-turbine generators)
DC motors
DC generators
Steam turbine generators
Hydro-turbine generators
Condensing machines
AC commutator motors
Submersible electric pumps
Motors for textiles
2.2.2 The characteristic code is the Chinese phonetic letters used to characterize the performance, structure or purpose of the motor. For explosion-proof motors, the letters representing the explosion-proof type, A (increased safety type), B (flameproof type), and ZY (positive pressure type), should be marked at the first position of the motor characteristic code, that is, immediately after the motor type code.
2.2.3 The design serial number refers to the design sequence of the motor product, which is expressed in Arabic numerals. For the product of the first design, the design serial number is not marked. The product derived from the basic series. Its design serial number is marked according to the basic series, and the special series products are marked according to the order of their own design.
2.2.4 The excitation mode code is respectively represented by the letter S for 3rd harmonic excitation, J for thyristor excitation, and X for phase compound excitation, and should be marked after the design serial number. When the design serial number is not necessary, it is marked after the feature code and separated by a short dash. 2.8 The specification code of the motor is represented by center height, core outer diameter, frame number, housing outer diameter, shaft extension diameter, flange code, frame length, core length, power, current level, speed or number of poles. The specification codes of the main series products are as specified in Table 2. If other series products really need to be represented by other parameters other than the above, it should be stated in the standard of the product. The length of the base is indicated by international letters, S for short base, M for 4 base, L for long base. The core length is indicated by the numbers 1, 2, 3** from short to long. The flange code is indicated by the international letters FF (flange with through holes or FT (flange with screw holes) together with the value of the center base circle diameter of the flange fixing hole.
