Problems solved by technology

[0003] Most of the traditional full superconducting motors use rotor superconducting excitation, and the superconducting power supply is powered by slip rings. At the same time, the superconducting motor is affected by the centrifugal force, and the power performance will be attenuated, which will affect the performance of the full superconducting motor, resulting in the failure of the full superconducting motor. Work at high speed, unable to meet the needs of aviation motors working at high speed
Moreover, the cooling of full superconducting motors generally adopts low-temperature immersion cooling or low-temperature conduction cooling, but the auxiliary structure of immersion cooling and conduction cooling is too large for the motor, which greatly reduces the high power density gain effect of full superconducting motors
