Technical Field

Background
In the current situation, the internal and external monopole radiation magnetic rings of the permanent ferrite are generally magnetized by adopting direct current electromagnets. The principle is that a closed loop is formed by an electromagnet and an additional iron block through constant-current direct current in a coil, so that the coil generates a constant magnetic field, exciting current flows through the coil to generate a magnetic field, and a magnetized body is placed in the magnetic field, so that the instant magnetization can be realized. The magnetizing process converts electric energy into magnetic energy, and the energy efficiency of the used electric energy is 50-60%.
Meanwhile, in general, a high-voltage direct-current electromagnet is adopted for magnetizing, and the high-voltage direct-current electromagnet is firstly converted into high-voltage direct-current by alternating current, so that the capacitor is charged, and the resistor coil is discharged, and the magnetizing is performed by instantaneously generating a strong magnetic field. When magnetizing, the current of the equipment is increased, the consumed power is also increased along with the increase of the current, energy is converted into a magnetic field in the magnetizing coil to magnetize products in the magnetizing coil, and meanwhile, redundant energy is generated in the magnetizing coil to consume heat after the instantaneous magnetizing products are magnetized and saturated. The magnetizing device is used for cooling the magnetizing coil by adding a water cooling system, otherwise, the magnetizing coil is damaged and the magnetic energy is reduced due to the fact that the temperature is increased after frequent use.
Through retrieval, the application with the Chinese patent publication number of CN 114613569A discloses a method and a device for axially magnetizing a permanent magnet ring. In the application, a permanent magnet ring module to be charged is placed in a magnetizing coil, and a shielding device is arranged in the inner circle area of the permanent magnet ring module to be charged; when transient current is applied to the magnetizing coil, the magnetizing coil generates an original magnetic field with the axial direction of the permanent magnet ring and the intensity being changed in the inner area of the magnetizing coil, the original magnetic field induces eddy currents in the shielding device to generate an additional magnetic field, and the direction of the additional magnetic field is the same as that of the original magnetic field in the area of the permanent magnet ring module to be charged; the additional magnetic field is overlapped with the original magnetic field, so that the intensity of the magnetizing magnetic field of the permanent magnet ring module area to be charged is increased, the permanent magnet ring module to be charged is axially magnetized, and the energy conversion rate is improved. The essence of this application is to accomplish the magnetizing operation by energizing the magnetizing coil. The problem that energy waste and temperature rise of a magnetizing coil are caused by the fact that redundant energy generates heat in the magnetizing coil after magnetizing and saturating a magnetizing product is solved.
