немецкий левитирующий поезд Transrapid
удивительный факт узнал
всегда думал что Трансрапид имеет свои колеса, на которых он ездит на малой скорости. Мне казалось, это было бы логично, для экономии энергии, ну и на случай аварии....
Оказалось
The superspeed maglev system has no wheels, axles, transmissions, or pantographs.... Electronic systems guarantee that the clearance remains constant (nominally 10 mm). To hover, the Transrapid requires less power than its air conditioning equipment. The levitation system and all onboard electronics are supplied by the power recovered from harmonic oscillations of magnetic field of the track's linear stator (Those oscillations being parasitic cannot be used for propulsion anyway) at speeds above 80 km/h, while at lower speeds power is obtained through physical connections to the track. In case of power failure of the track's propulsion system Transrapid car uses on-board backup batteries that can supply power to the levitation system.
