What is the Principle of Hover Cars?
1 Answers
The principle of hover cars is that a rotary engine is installed in the middle of all wheels, and two magnets are mounted on the outer side of the wheels. When the wheels rotate, the magnetic field on the aluminum road surface changes, generating an induced current. The interaction between the road's magnetic field and the magnets on the wheels produces both lift and propulsion. The first hover car was developed in Japan. A miniature maglev car model, measuring 52 cm in length, 23 cm in width, 14 cm in height, and weighing 4 kg, successfully conducted a driving test on a 26-meter straight track, reaching a speed of 25 km/h. When the speed exceeded 10 km/h, the car model hovered 6 to 7 mm above the road surface, moving forward exceptionally smoothly. The Volkswagen hover sphere relies on the abundant magnetic ore veins underground to provide levitation power. However, the distribution of magnetic poles in these ore veins is irregular, utilizing the principle of like poles repelling each other to achieve levitation. To use permanent magnets with fixed magnetic poles, superconducting electromagnets must be employed. There are two types of maglev systems: the German normal-conducting type and the Japanese superconducting type. The advent of hover cars has sparked a revolution in the automotive industry, utilizing electromagnetic levitation technology, which involves generating eddy currents on the surface of metal objects through high-frequency electromagnetic fields to achieve support.
