The principle of magnetic levitation is actually not very complicated. In short, it is based on electromagnetic levitation technology, plus a wireless conductive magnetic levitation inductance coil. This magnetic levitation inductance coil is the transmitting and receiving device, and the coil installed on the base is the transmitting device. It is the receiving device. However, many companies or manufacturers can't do it, because there is already one or two magnetic fields in the suspension system, including the magnetic field generated by the ferrite and the magnetic field generated by the induction coil. If you add a transmitter coil, you can There will be another magnetic field, and certain technology is needed to reduce the interference between these magnetic fields. We know the principle of magnetism, and we know that electricity generates magnetism, and the two can be converted into each other. A magnetic field will be generated in the induction coil. The magnetic fields in the device form a transmitting and receiving effect with each other.
The magnetic levitation inductance coil uses the principle that the magnetic poles repel each other and opposites attract each other. There is a permanent magnet on the bottom and a permanent magnet on the top. The same polarity is placed opposite to each other, and a repulsive force will be generated. When the repulsive force is greater than or equal to the weight of the upper permanent magnet, the magnetic levitation However, the magnetic levitation generated by 2 permanent magnets is very unstable and requires external force control, so a coil is required. When current passes through the coil, a magnetic field is generated around the coil. This additional magnetic field can generate an external force on the upper permanent magnet , or push or suck. Stable magnetic levitation state.
Magnetic levitation inductance coils are made of toroidal cores, made of iron powder, ferrite, winding or other materials for horn inductance. Longitudinal magnetic field coils are used in a wide range of applications such as high frequency coils and transformers. Similar to the same solenoid coil Soft magnetic inductors can have higher Q-factors and higher inductance configurations than are possible. This is mainly due to the fewer turns required to provide a closed core magnetic circuit. At high permeability, this flux is limited In the core, and the energy dissipated due to confinement is reduced and can be absorbed by nearby objects, the ring provides some core. The magnetic field flux direction is geometrically in the center of the threaded ring, while the soft magnetic flux direction is parallel to the magnetic field of the ring core.
