A current lead assembly for a superconducting motor comprises an epoxy base, a first copper lead, a second copper lead, a third copper lead, a fourth copper lead and a copper cover plate. Four mounting sides of the epoxy resin are used for mounting the copper leads and include two concave sides and two convex sides. The first copper lead is mounted on the first concave side. The second copper lead is mounted on the first convex side. The third copper lead is mounted on the second concave side. The fourth copper lead is mounted on the second convex side. The current lead assembly can be serially connected with three superconducting coils; the superconducting coils are sequentially connected with the four copper leads; a superconducting tape of every superconducting coil is serially connected to the copper leads by welding and is fastened with the copper cover plate.
