The crgo lamination transformer is mainly composed of a core (or core) and a coil. The coil has two or more windings, wherein the winding of the power supply is called the primary coil, and the other winding is called the secondary coil. It can change the AC voltage, current and impedance. A simple core transformer consists of a core made of a soft magnetic material and two coils of different numbers placed on the core.
Principle of crgo lamination transformer
The role of the core is to strengthen the magnetic coupling between the two coils. In order to reduce the eddy current and hysteresis loss in the iron, the core is laminated by a lacquered silicon steel sheet; there is no electrical connection between the two coils, and the coil is wound by an insulated copper wire (or aluminum wire). One coil is connected to the AC power source called the primary coil (or the primary coil), and the other coil is called the secondary coil (or the secondary coil). The actual transformer is very complicated, and copper loss (coil resistance heat generation), iron loss (core heat generation), and magnetic flux leakage (air-closed magnetic induction line) are inevitably present.
