Embodiment Construction

[0015] A six-phase statically sealed high-temperature superconducting motor, such as figure 1 As shown, including the stator 1 and the rotor 4 located in the stator 1, the stator 1 and the rotor 4 are both salient pole structures, and the stator 1 is provided with 24 salient poles, which alternate along the circumferential direction of the stator 1 on the salient poles of the stator 1 Twelve armature windings 3 and 12 field windings 2 are wound; the armature windings 3 are directly wound on the salient poles of the stator 1, and two adjacent armature windings 3 along the circumferential direction of the stator 1 form one phase, The 12 armature windings 3 constitute 6 phases in total. The armature winding 3 is a copper winding wound on the salient pole of the stator 1; the excitation winding 2 is wound by a high temperature superconducting wire. The rotor 4 is provided with 25 or 23 salient poles.

Abstract

The invention relates to a six-phase static sealing high-temperature superconducting motor, which comprises a still stator and a rotating rotor, wherein the rotor is located in the stator; the stator and the rotor are in a salient pole structure; salient poles of the rotor are outward; the salient poles of the stator are inward; the stator is provided with 24 salient poles; the rotor is provided with 23 salient poles; an air gap is reserved between the stator and the rotor; and 12 armature windings and 12 high-temperature superconducting excitation windings are alternately wound on the salient poles of the stator along the circumferential direction of the stator. The six-phase static sealing high-temperature superconducting motor improves the power level of the motor, reduces the cost and the control difficulty of a power converter and achieves static sealing of a cooling medium. The six-phase static sealing high-temperature superconducting motor is simple in structure, low in cost, good in cooling effect and high in operation reliability.

Description

technical field [0001] The invention relates to a high-temperature superconducting motor, in particular to a six-phase statically sealed high-temperature superconducting motor. Background technique [0002] In recent years, with the rapid development of high-temperature superconducting technology, high-temperature superconducting materials have been widely and deeply studied in the fields of motors, flywheel energy storage, and magnetic levitation. Existing research data show that under liquid nitrogen cooling conditions, the capture magnetic field of high-temperature superconducting bulk materials can reach 2.3T (77K), which is much higher than the magnetic field strength of current permanent magnets, while the second-generation high-temperature superconducting Y-series wires have The critical current density has also reached 3×106A / cm2 (77K, 0T). This means that replacing the windings and permanent magnets in traditional motors with high-temperature superconducting materi...
