A new form of transportation that uses superconductivity to propel itself.
Superconductivity is a phenomenon in which the electrical resistance of a certain metal becomes zero when its temperature is lowered below a certain point, and once an electric current flows through it, the current continuously flows through the coil and generates a strong magnetic field due to the lack of resistance.
The device that generates the superconductivity, called a linear motor, is attached to the chassis and the propulsion path, and the magnetic field generated by the device is converted into propulsion power by using the forces of attraction and repulsion.
Linear motors themselves are currently used in some subway trains as a dynamic force supplement to accommodate inclines and curves, and these are called steel-wheel-type linear motor trains.
However, what is generally referred to as a linear motor train is a superconducting magnetic levitation (A.K.A. maglev) type linear motor train, which uses a linear motor to provide all of its propulsion force, and is so named because the repulsion and attraction of the magnetic force cause the car body to levitate during propulsion.
It is said that maglev-type linear motor trains can travel at speeds of up to 500 km/h, which, when commercialized, will make it possible to travel between Tokyo and Osaka in only about an hour. In Shanghai, a maglev-type linear motor train has been in operation since January 1, 2004.
