1 Scope
This standard specifies the compilation method for model of rotating electrical motor.
This standard is applicable to compilation for model of various rotating electrical motors (excluding control motor).
2 Compilation Principle for Product Model
2.1 Product model is a kind of code used for the convenience of business contact, simplifying product name, specification and type in technical documents for the use, manufacture and design departments etc. , it shall be simple and non-repetitive.
2.2 Product model is composed of the Chinese pinyin letters, international symbols and Arabic numerals.
The Chinese pinyin letters shall be selected according to the following principles:
——As for the Chinese character representing the meaning in the product name, take the first letter of its pinyin;
——If the above letters cause repetitive model or cannot be adopted because of other difficulties, the first letter of the pinyin of other Chinese characters for the product name may be adopted;
——If it is really difficult, other letters may be selected.
3 Compilation Method for Product Model
3.1 Product model is composed of product code, specification code, special environment code and supplementary code etc., and shall be arranged according to the following sequence:
... ...
... ...
Note: In case of smaller nameplate and long model, for example, when it will not cause confusion between the numbers and letters of product code, specification code, special environment code and supplementary code, this short dash may be omitted.
3.2 The product code of rotating electrical motor is composed of the type code, feature code, design number and excitation mode code of electrical motor.
3.2.1 As the Chinese pinyin letters adopted to represent the various types of rotating electrical motor, type code shall comply with the requirements of Table 1.
