At this time, the frequency of the induced voltage generated by the vehicle-mounted electric energy receiving coil is fe. When the vehicle-mounted superconducting coil runs in a high-speed domain, extra current control on the ground zero-flux coil is not needed, and the vehicle-mounted superconducting coil is driven by the ground propulsion coil to rotate at a speed vsThe ground zero-flux coil generates induction current under the action of the vehicle-mounted superconducting coil, a fundamental magnetic field in a space magnetic field generated by the induction current is used for ensuring the stable suspension of the train, and a 5-time space harmonic magnetic field with the largest ratio in the harmonic magnetic field is opposite to the train
