High-temperature superconducting linear synchronous motor

The invention discloses a high-temperature superconducting linear synchronous motor. The motor comprises a stator part and a rotor part, and further comprises an excitation switch, the rotor part comprises a plurality of multi-turn high-temperature superconducting coils, the adjacent high-temperature superconducting coils are connected in series reversely, the two ends of each superconducting coilare used for being connected with an external excitation power supply, and the excitation switch is connected to the two ends of each superconducting coil in parallel; by utilizing the zero-resistance characteristic of the high-temperature superconductor, the high-temperature superconducting coils are pre-excited by the excitation switch to be electrified, and the currents of the high-temperaturesuperconducting coils are not attenuated in the working process, so that the loss of the conductor coil is reduced, the reactive power of the motor is reduced, and the synchronous operation of the rotor coil without an external excitation power supply is realized; when the high-temperature superconducting coils are reversely connected in series, the directions of thrust generated by the adjacenthigh-temperature superconducting coils under the combined action of the traveling wave magnetic field and the mover current are consistent, the total thrust on the mover can be increased, and the rapid acceleration performance of the pulse power type linear motor is achieved.
