All coil winding is enamelled wire. If it's not enamelled, it shorts out. Enamelled wire generally selects the diameter of the line, which is the thickness.
Problem four: How to make mobile phone wireless charger All the coil winding is enameled wire. If it's not enamelled, it shorts out. Enamelled wire generally selects the diameter of the line, which is the thickness.
First prepare three Dongdong: one is the United States wireless coil, the other is the United States wireless charger also known as wireless energy disc, two lacquer bag money. To do a modification requires a certain amount of hands-on ability and hands-on equipment, such as: multimeter, soldering iron and solderLet's wait.
Wrap the enameled wire around the prepared cylindrical shape object, the number of turns wrapped according to the formula of electromagnetism, remove the wound coil and fix it with absolute glue, leaving the head and tail in the knife to scrape off the enameled wire head and tail paint to leave copper wire. Drill a hole in the bamboo section as large as the USP data cable.
Enamelled wire good. Due to the skin effect of the high-frequency signal in the wire, which means that the high-frequency current in the wire will converge to the surface of the wire, the wireless charging coil generally uses a multi-strand enamelled wire to reduce the impedance.
Wireless charger refers to the use of electromagnetic wave induction principle for chargingDevices, similar in principle to transformers.
The steps are as follows: First cut the end of the USB data cable connected to the mobile phone with scissors or a knife, and then cut a short section of the long end of the data cable into the incision, you will see four green, red, white and black wires, cut the green and black two, and cut a small section of the insulation layer of the red and green two, respectively, to expose the copper wire.
Open the smart handThe back cover of the machine, then take out the wireless charging receiver ready; Or the protective layer of double-sided tape peel; The next task is to connect the receiver's metal shock to the smartphone battery, which is the most difficult part of the process. However, as long as you are careful to ensure that each metal shock is connected together, it can be done.
Question 1: How to make wireless charger? There are many ways to use wireless chargers, mainly to see how the reception is installed. But no matter what the product is close, the operation method is placed on the launch plate. Take mobile phones as an example, today's mobile phones are generally plus a mobile phoneJacket. Inside this jacket is a wireless receiver module. The phone can be charged wirelessly with this jacket.
Wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer.
The principle is very simple, stick the charging coil inside the mobile phone battery cover, paste the screen wallpaper, and then connect the positive and negative electrodes to the mobile phone usb power supply. You can put your phone on the Touchstone transmitter and charge it wirelessly.

When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.

Since the energy is transmitted by inductive coupling between the charger and the electrical device, there is no wire connection between the two, so the charger and the electrical device can be no conductive contact exposed. Wireless charging mainly uses the principle of electromagnetic induction, magnetic resonance and radio wave technology.
