Smart watch coil
Watch inductor coil is also known as smart watch coil or watch coil, is one of the coils. Watch coil structure mainly includes an iron core and directly wound in the iron core of the enameled wire, hollow inductance coil core includes both ears and the middle of the core rod, the ear in the core rod behind the protrudes, the enameled wire layer by layer tightly wound in the iron core, of which, the gap between the inner layer of enameled wire and the iron core is 0 ~ 0.015mm, The winding thickness of enameled wire is 5 ~ 55 layers. No insulating medium such as insulating coating, insulating paper, and insulating coil holder is provided between the iron core and the enameled wire. The current technology has realized the direct winding of the coil on the coil core, greatly increasing the torque of the electromagnetic coil and reducing the coil energy.
Wireless charging technology for low-power wireless charging often uses electromagnetic induction type, high-power wireless charging often uses resonance type by the power supply device (charger) to transmit energy to the electrical device, using the received energy to charge the battery, and at the same time for its own operation, because the charger and the electrical device to transmit energy by magnetic field, Therefore, chargers and electrical devices can be no conductive contact exposed, hollow inductor wireless charging technology has been widely used in daily life, has become a very important technology in modern life.
