Provided is a current lead wire using a superconducting tape. The current lead wire may comprise a first superconducting tape that electrically connects the first terminal and the second terminal; a second superconducting tape that is arranged in parallel with the first superconducting tape to electrically connect the first terminal with the second terminal; and a third superconducting tape that electrically connects the first superconducting tapes with the second superconducting tape.

Superconducting tape current leads

A superconducting synchronous motor having a simple and stable structure is provided. The superconducting synchronous motor according to one embodiment of the present invention comprises: a rotary shaft; a rotation core mounted at the rotary shaft so as to be rotated by connecting with the rotary shaft; and hooked magnetic poles extending from one end of the rotation core in a longitudinal direction. Each of the hooked magnetic poles is composed of first and second inductors of a magnetic material alternately engaged with each other and a superconducting wire to be wound, and comprises a first superconducting field winding and a second superconducting field winding fixed closely at the other end of a first inductor rotation core and the other end of a second inductor rotation core, respectively. Each of the first superconducting field winding and the second superconducting field winding excites the first inductor and the second inductor to different poles.
