A nameplate is a nameplate that is fixed on the product after it is put on the market to provide users with information such as manufacturer trademark identification, brand distinction, and product parameter inscription. The nameplate is also called the nameplate. The nameplate is mainly used to record some technical data of the manufacturer and rated working conditions for correct use without damaging the equipment.

The materials used to make nameplates are divided into metals and non-metals: metals include zinc alloy, copper, iron, aluminum, stainless steel, etc., but aluminum is mainly used in production because of the effect of the processed nameplates. It is relatively high-end, durable and does not rust. Non-metals include plastic, acrylic organic board, PVC, PC, paper, etc.

Nameplates are divided into concave and convex nameplates and flat nameplates. For ordinary concave and convex nameplates, the paint filled in the concave part is nitrocellulose paint. The method of painting is to spray paint the entire front of the nameplate, and then remove the paint from the font or pattern parts to expose the metal lettering or pattern lines. Higher-grade concave and convex nameplates are simply coated with baking paint, or partially painted with colored paint, or coated with transparent varnish, depending on the requirements. Flat nameplates are mainly made of aluminum alloy materials. The color on the surface is not paint, but the color dyed after anodization. Depending on the process method, it can be a single color or 2-3 colors. of. Flat nameplates have higher decorative properties and are cheaper. There are also nameplates that are printed on the silk screen, and the color used is ink;. Imitation gold card: The color of the card is dull, and the surface of the card is prone to fading and staining over time. Real gold cards are only golden in color at the time, and will lose their real gold color over time.

And it can maintain the characteristics of the product that will never fade.

Domestic motor models are generally represented by uppercase English Pinyin letters and Arabic numerals. The format is: the first part uses uppercase Pinyin letters to represent the product code, the second part uses Arabic numerals to represent the design serial number, and the The third part uses Arabic numerals to represent the frame code, and the fourth part uses Arabic numerals to represent the armature core length code. We can see the following terms on the nameplate of the electric energy meter: single-phase, three-phase, active power, reactive power, etc. The nameplate is also marked with the registered model number: such as DDS×××, the first D is the pinyin prefix of "electric energy meter", the second D is the pinyin prefix of "single-phase", and S is "static (commonly known as electronic (formula)" is the prefix of static in English. “×××” represents different types of meters produced by different companies.
