Abstract

The invention relates to a high-temperature superconducting induction motor stator. First to sixth parts of the stator structure are respectively placed in first to sixth opened rectangular grooves; first two sixth copper coils are respectively embedded at the notches of the first to sixth opened rectangular grooves; the parts, extending out of the end part of a stator core (1), of the first to sixth copper coils circumferentially and respectively bend along the inner diameter of the stator core (1) so as to prevent end coils from intersection, and cannot contact first to sixth superconducting coils. According to the stator, the problem that relatively large pulsating torque is generated as the arrangement and fixation of the superconducting coils in a stator slot are difficult and the superconducting winding coefficients are too low overcome, superconducting coil fixing frames are prevented from generating eddy-current loss, the superconducting cooling cost is reduced, the volume and weight of a superconducting motor are greatly decreased, and the power factor and efficiency of the motor are improved.

Description

technical field [0001] The invention relates to a stator of a high temperature superconducting induction motor. Background technique [0002] The superconducting motor arranges the superconducting windings in the stator slots, while the ordinary superconducting motor arranges the superconducting windings in the rotor slots, which brings about the dynamic sealing problem of the cooling system. Due to the limitation of the radius of curvature of the superconducting strip when making racetrack superconducting coils, a non-stacked winding structure with fewer slots per pole and phase is generally used, so the arrangement of superconducting coils in the stator slots is limited, resulting in If the winding coefficient of the superconducting induction motor is too low, a large pulsating torque may be generated, which makes it difficult to fix the superconducting coil in the stator slot, and the performance of the superconducting motor is greatly reduced.
