The main use of non-oriented electrical steel is to make electrons and rotors for electrodes. But the thickness of non-oriented electrical steel is from 05~0.2 have, ** also from thousands to more than 10,000, what thickness of electrical steel to choose.
First of all, the thinner the thickness, the smaller the eddy current loss, that is, the more energy saving. Is it just a matter of choosing the thinnest for all motors?
One is that the thin electrical steel is processed, and the speed is definitely a little slower than that of the later electrical steel, which affects the stamping efficiency.
Second, for steel mills, the thinner the electrical steel, the higher the production cost, and the more expensive it is.
For some motors, the size is not so important, and there is a better heat dissipation environment, so there is no need to consider particularly thin electrical steel.
Like drones, which need to fly in the sky and need batteries to drive the motor to rotate, they need to be very energy-saving, because the battery itself is its own weight, so it is generally selected to be particularly thin electrical steel. UAVs generally choose 02mm electrical steel.
For new energy vehicles, 03-0.35mm electrical steel.
For some large-scale electrical equipment, 05 mm of electrical steel.
After choosing the thickness of the electrical steel, the iron loss of the electrical steel is selected, the lower the iron loss, the higher the iron loss, and the selection of all industrial products must be considered.
In the end, the most cost-effective industrial product will win the competition. Therefore, the choice of electrical steel grade is ultimately the choice of cost performance. Motors
