Motor, transformer, made of silicon steel sheet of various shapes of iron core, the main use of silicon steel sheet of what performance?
The main use of silicon steel sheet excellent magnetic conductivity, because the transformer, motor, winding is the passage of electricity, the iron core is the magnetic path. The transformer works only through electromagnetic conversion of the motor. The motor is designed based on this principle.
Should be the magnetic properties, the specific parameter is called magnetic permeability, magnetic materials of different permeability, and for the same kind of magnetic material, its permeability is not constant, but varies with the magnetic field intensity, reflect the change curve is called basic magnetization curves, hysteresis loops can also reflect this in addition, considering the characteristics of magnetic materials and make full use of the contradiction between the no-load current is too large, often the magnetic material is the most suitable working point is set to the knee point, can be seen from above different magnetic materials have the same knee point. Generally speaking, magnetic materials include iron, cobalt and nickel. But while silicon ferrosilicon alloy containing silicon, carbon, after long practice, that the use of steel in the traditional motor can achieve good technical and economic effect, it is generally use cold rolled silicon steel sheet as the core material, above all, should use the magnetic properties of silicon steel sheet can.
