The invention discloses a coreless type megawatt superconducting
motor system. The coreless type megawatt superconducting
motor system comprises a superconducting rotor of coreless structure, wherein the superconducting rotor of the coreless structure comprises a coil skeleton, superconducting excitation coils and a
torque tube connected with the coil skeleton, the superconducting energizing coils are wound around the upper surface and the lower surface of the coil skeleton and wound in
convolution U structure, each two adjacent effective excitation edges are parallel to each other and respectively form a positive pole and a negative pole in a pair of
magnetic poles, the effective excitation edges of the superconducting energizing coil wound around the upper surface of the coil skeleton and the effective excitation edges of the superconducting energizing coil wound around the lower surface of the coil skeleton are symmetric around the coil skeleton, and exciting current directions of each two effective excitation edges which are symmetric around the coil skeleton are the same. Compared with the prior art, the coreless type megawatt superconducting
motor system has better excitation effects and mechanical properties than a track type
excitation coil through structure design of the superconducting excitation coils, the support skeleton of the superconducting excitation coils and the
torque tube, and can commendably solve the problems of excitation effect reduction, mechanical
stress change and support protection reduction of the superconducting excitation coils, generated after iron cores are removed.
