電工鋼硅鋼片Electrical steel, also known as silicon steel sheet, is an indispensable metal material in the power, electronics, and military industries, and is also the largest functional material in production. It is mainly used as the iron core for various motors, generators, and transformers. Specific total loss (iron loss) is the total power consumed per unit mass of material when the magnetic polarization waveform remains sinusoidal, with a specific peak and frequency. The specific total loss is represented by the symbol P (Jm/f), in W/kg. Example: P1.5/50 represents the specific total loss at a maximum magnetic polarization intensity of 1.5T and a frequency of 50Hz. 3.2 Magnetic Polarization Q/BQB 480-20212 Magnetic polarization intensity refers to the peak magnetic polarization intensity of a specific magnetic field intensity when a sample is subjected to alternating magnetization. Its symbol is J (H), and the unit is T (Tesla). Example: J5000 represents the peak magnetic polarization intensity corresponding to a magnetic field intensity peak of 5000A/m. The material grades in this document are classified based on the nominal maximum specific total loss P1.5/50 (W/kg) at a magnetic polarization strength of 1.5T and a frequency of 50Hz, as well as the nominal thickness of the material. They are further divided into three categories based on product characteristics: ordinary type, stress relief annealing type, and high-efficiency type. Example 1: B35A210 represents a common non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 2.10W/kg； Example 2: B35AR300 represents a stress relieved annealed non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 3.00W/kg； Example 3: B35AH230 represents an efficient non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg. Example 4: 35WW210 represents a normal type WW non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.10W/kg. Example 5: 35WH230 represents an efficient WH non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg.
