2, conductive slip ring in the electrical design process, when the mechanical part of 360 degrees unlimited continuous rotation, the wire needs to be connected to the rotating parts, electrical engineers will encounter the wire winding problem, this time, wireless charging motor he needs an electric rotary connector, commonly known as the electric slip ring to transmit power and signal rotary connection. It can improve the performance of the system, simplify the structure of the system, and avoid the sprain caused by the wire in the process of rotation.
3, the first kind, when repairing the motor to remove the old line, write down the number of turns of each groove, measure the diameter of the lower line, and then clean the notch and pad the insulating paperPlay the wire, down to the slot, and then seal with a bamboo skewer, if the new line, according to the stator data according to the data check the wire diameter and the number of turns.
Principle of wireless chargingMainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
Using the principle of electromagnetic induction charging equipment, the principle is similar to the transformer, through the transmitter and the receiving end of the coil, the transmitting end of the coil under the action of power to send an electromagnetic signal, receive>There are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
2, mobile phone wireless charging is achieved by using wireless charging technology, there are mainly the following ways wireless charging motor : Qi wireless charging: Qi is aIt's a wireless charging standard that many phones and chargers support. Wireless charging can be achieved simply by placing the phone on a charger or wireless charging dock that supports the Qi standard.
3, the fourth: electric field coupling wireless charging, this charging method is through a vertical way of asymmetric dipole to generate current transmission, this charging method conversion rate is very high, the position of the two can also not be fixed, but there is a big disadvantage, that is, the need for equipment larger volume, power is particularly small.
4, electromagnetic induction is the most common wireless chargingThe way is to use the principle of electromagnetic induction, through the primary and secondary coil induction to generate current, so as to transfer energy from the transmission end to the receiving end. This realization has been achieved by the Wireless Charging Alliance (Wireless Wireless charged motor ? The Power? Consortium; WPC).
5, electromagnetic induction. This is the more common way of working wireless chargers, which uses the principle of electromagnetic induction to generate current through electromagnetic induction between the primary and secondary coils, so as to achieve the transfer of energy in the space; The implementation of this wireless charger has been promoted by the Wireless Charging Alliance.
6, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
1, according to the principle, it is possible to make the micro motor run, but the micro motor needs to have a charging acceptance device.
2, the first is calledTesla, may be more people hear the name is Elon Musk to build the electric car, but this is also a personal name, the full name is called Nikola Tesla, it can be said that he is the most outstanding scientist and inventor in human history.
3, because the 030 motor has the advantages of small size, light weight and high power, it is widely used in some small electronic products. Such as toy cars, power tools, small robots and other fields. At the same time, in camera modules, car cameras, wireless chargers, VR glasses and other equipment, 030 motor is often used as a powerThe source. It can be said that the 030 motor has become an important member of the field of micro DC motors.
1, wireless charging, even remote sensing charging. Its principle is electromagnetic induction, which is usually used in small power situations and does not require electrode contact points. There is an induction coil in the column and the electric toothbrush is inserted into the partThere are also induction coils, there are plastic insulation outside, there is no electrical contact, induction to obtain electrical energy to charge the battery to drive a small motor.
2, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. 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.
3, charge I use this electric toothbrush is noLine induction charging, that is, the toothbrush can stand on the charging adapter (the principle is like wireless charging of mobile phones). I think this is particularly good design, because there is no direct contact with electricity, so it is particularly safe. If the waterproof electric toothbrush is charged directly through the 220V power supply, the waterproof function I think is particularly necessary.
2, open the wireless reverse charging method: you can enter the phone Settings -- battery -- more Settings -- open the "wireless reverse charging", open the peripherals can provide up to 10W charging power supply for quick charging. vivo/iQOO currently supports wireless charging models: X80Pro Snapdragon version, X80Pro Guet version, XFold, XNote, iQOO9Pro, X70Pro, iQOO8Pro; No need to open, use a wireless charger.
3, set the vivox80pro in the motor battery. Select the wireless charging option on the battery screen. Connect the wireless charger to the power supply and put the back of the phone on the wireless charger.
4, vivo wireless charging function openedHere's how: First, make sure you have a wireless charger that is compatible with the Qi standard. Then, follow these steps: Place the vivo phone in the proper position of the wireless charger.
5, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
6, the function cannot be enabled. At present, the models that support wireless reverse charging are: iQOO 11 Pro, X90Pro, X90 Pro, X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
