Talking about the magnetizing circuit inside the magnetizing machine

It can be said that a permanent magnet used in most of the current motors is manufactured by a magnetizing machine. Regarding this kind of machine, the magnetic field generated by high-voltage electricity is mainly used for the magnetic objects in the field. Magnetizing, so that the magnet is permanent magnetized, this is the function of this kind of machinery, and this kind of generated magnet is also the auxiliary power device that is currently used in many equipment, including automatic rotor winding machines. This device is used to increase the winding speed of the winding machine. In addition, this kind of auxiliary device is also used in the commutator finishing machine to improve the refined processing. And what is the circuit in this magnetizing device? Here is an introduction to the magnetizing circuit. The magnetizing circuit has a main circuit and a trigger circuit. The circuit of the magnetizer is actually made up of a variety of circuit equipment for roommates. The main circuit is mainly composed of AC voltage regulation and boost, rectification, energy storage and discharge circuits.

    The input voltage of the step-up transformer t is adjusted by adjusting the phase shift angle (or conduction angle) of the triacs vt1 and tv2, and then the pulsating DC voltage is obtained through the bridge rectifier circuit, and the electric energy is stored in the capacitor group cl. When the thyristor vt7 is turned on, it instantly generates a strong pulse current discharge to the magnetizing head to quickly magnetize the material. In the triac synchronous phase control trigger circuit, the output terminal voltage vout of the analog quantity module fx0n-3a controls the conduction angle to adjust the upper end voltage of the energy storage capacitor.
