Abstract: An assemblable modular and disc coreless permanent magnet superconducting ultra-efficient motor comprises a junction box, a housing, bearings, a rotating shaft, rotors, a stator, and air gaps; the housing comprises a left and a right end cover, the rotors comprise a left and right rotor; both left and right rotor comprise 2N pairs of left or right rotor poles and rotor yokes; the stator comprises a stator armature disc and stator windings, the bearings comprise a left and right bearing, and the air gaps comprise a left and right air gap. The rotor's magnetic field is replaced by high-temperature resistant rare earth high-intensity permanent magnets, and the rotor's electrically excited magnetic field is replaced by permanent magnets, eliminating rotor's copper and iron losses. The winding superconducting wires eliminate stator's copper loss, and stator iron core removal eliminates stator's iron and magnetic saturation loss, improving the efficiency and torque output.
