insulation In mobile devices such as smartphones for wireless charging, the receiving coil and ferrogen insulation require as thin a magnet as possible. However, the properties and thickness of magnetic materials need to be carefully designed.
This is because if the magnetic sheet is too thin, it can cause magnetic saturation problems. In the event of magnetic saturation, the inductance of the coil will suddenly decrease, which may cause obstacles to the wireless charging process.
At the same time, wireless charging insulation, depending on the receiving coil mounting site, may also cause abnormal heat. The electronic labels packaged into special anti-magnetic absorbent materials of anti-metallic absorbent materials technically solve the problem that electronic labels cannot be attached to metal surfaces. Products can be waterproof, acid-proof, alkali-proof, collision-proof, can be used outdoors. Zero-speed chassis on the stability of power operation performance, has a considerable impact on the built-in intelligent management system, to achieve the monitoring and adjustment of each part of the power supply parameters, which also supports the fan's various operating modes to define mute, efficiency, zero-speed and other fan mode settings. For example, if the receiving coil is located close to the battery, the magnetic sheet will not be able to fully utilize the magnetic shielding characteristics, allowing high-frequency flux to run through the magnetic sheet until it reaches the battery case.
In general, the material quality of the battery box is aluminum, high-frequency flux will cause the surface of the box to produce eddy current (also known as Fuco current), and the resulting iron damage will not only reduce the efficiency of power transmission, but also may cause abnormal heat.
In particular, it is important to ensure that the magnetic shield is safe on the receiving coil side of the magnet positioning method. Zero-speed chassis on the stability of power operation performance, has a considerable impact on the built-in intelligent management system, to achieve the monitoring and adjustment of each part of the power supply parameters, which also supports the fan's various operating modes to define mute, efficiency, zero-speed and other fan mode settings. This is because in this way, in addition to the high-frequency flux output from the transmitting coil, the flux from the magnet needs to be absorbed and shielded. Closely related to magnetic shielding properties are soft magnetic materials for magnetic sheets.
