System principle: Transformer is a device that changes AC voltage by using electromagnetic induction principle. The product is developed with reference to the latest CNC servo system parameters. The basic function of the conventional transformer is to change the input voltage to the output voltage, so that the equipment with different grid voltage in different countries can achieve the purpose of universal matching through the voltage conversion of small transformer. The main components are primary coil, secondary coil and core (silicon steel sheet). In electrical equipment and wireless circuit, it is often used for voltage rise and fall, matching impedance, safety isolation, etc. Transformer is a kind of static electromagnetic device, which can convert the alternating current energy of one voltage into the alternating current energy of another voltage at the same frequency. The main components of transformer are a core and two or more groups of wire groups sheathed on the core. The coil connected to the input power supply of the transformer receives AC energy, which is called primary line group or primary line group. The coil connected with load sends out AC energy, which is called secondary line group or secondary line group.
