Transformer production principle

Most transformers have a fixed core, the once and twice around the coil. Iron-based high-permeability material, most of magnetic flux confined to the core, the result, two coils to get a very high degree of magnetic coupling. In some Electric Motor, coils and between the two cores tightly integrated, its first and second voltage ratio is almost the same between the two coil turns ratio. Therefore, the transformer turns ratio, generally as a boost or step-down transformer of reference.

As the boost and buck function, making the transformer has become an important adjunct of modern power system to enhance the long-distance transmission of electricity transmission voltage makes more economical, as step-down transformer, which makes use of electricity has become more diversified, you can this said, there is no transformer, modern industry can not achieve real status of the current development. In addition to smaller electronic transformer, the Induction Motor and electronic transformers in between, and there is no clear dividing line. Generally provide 60Hz power supply networks are very large, it may be, covering half the capacity of Africa region is so large. Power electronic devices limit, usually limited to rectification, amplification, and the ability of other system components, some of which were part of an enlarged power, but with the power system generating capacity as compared to, it is still vested in the range of small power.

In the generator, whether it is the magnetic field or magnetic field through the coil movement movement through the fixed coil, can EMF in the coil, the two cases, the flux values ??are the same, but the number of coil flux intersecting chains there change, this is the principle of mutual induction. Hydraulic motor is a kind of mutual use of electromagnetic induction, transforms the voltage, current and impedance of the device.
