In the motor, the AW470 is a short for silicon steel! I want to know what it is, what's the difference between DW360 and that?
The silicon steel is divided into different grades according to the value of iron loss, the thickness and the test conditions. The symbolic meaning of its brand is as follows:DR - hot rolled silicon steel sheet for electrical purposes.DW- stands for cold-rolled silicon steel sheets for electrical purposesG - a steel plate tested at a frequency of 400Hz in a strong magnetic field.G - free grades - steel plates tested at a frequency of 50Hz in a strong magnetic field.After the letter "DR" number - the horizontal line before the number is 100 times the value of iron loss, the line after the figure is 100 times the thickness value.
The amount of silicon containing silicon for low silicon steel (silicon content of W is less than or equal to 2.8%) and Gao Guigang (silicon w > 2.8%).
