Hollow inductor
The hollow inductor coil consists of two parts, that is, the hollow coil. Hollow, as the name suggests, the center is nothing, the coil is one wire after another, the wires are insulated from each other, when the current flows through the wire, the magnetic field will be generated around the coil, the strength of the magnetic field is proportional to the strength of the current flowing through the coil and the number of turns of the coil. Similarly, in a certain magnetic field, the coil is used to cut off the role of the magnetic field line, the same magnetic field can be converted into electrical energy, using this magneto-electric conversion principle can be made into relays, motors, motors, wireless devices, horns and other equipment. The wire material can be copper, iron, aluminum, gold and other metal devices, the center of the coil can be inserted into the metal magnetic device to enhance the magnetic field generated when the conduction current, when the center of the coil only plastic skeleton or no skeleton to form a hollow coil, hollow inductor coil is widely used, in order to meet various needs, people design it into round, square, oval and various shapes.
Hollow inductors are mainly used in all kinds of toys, vehicle equipment, POS computer hard disk, high-end headphones, IC binding machines, high-speed textile machines, medical devices, military communications, coffee heating machines, RFID identifiers, cameras, cameras, switches, motors, motors, solar energy, wireless chargers, new energy automotive products, etc.
