Abstract

The invention relates to the field of superconducting technologies and the field of motor technologies, and particularly relates to a high-temperature superconducting motor. The motor comprises an electromotor and a generator, an armature winding is manufactured by winding a high-temperature superconducting wire, and a current passing through the armature winding has an alternating component. A refrigerating Dewar vessel of the motor is placed on the outside of a stator core, and cools a high-temperature superconducting coil in a contact conduction refrigerating mode. No heat insulating layer is arranged between a stator and a rotor of the motor, and an inner cavity of the motor is pumped as a low-vacuum cavity, so that no heat convection and no heat conduction are formed between the stator and the rotor. The torque transmission between the inside and outside of the vacuum cavity is realized through a magnetofluid sealing part. Stator windings are distributed in a centralized winding form. The coil adopts a runway coil or a rounded square coil, and no space mutual-interference situation occurs at the end part of the coil; a low-frequency alternating current is used, so that the loss is reduced; and due to the low-frequency characteristic, the motor is especially applicable to the fields such as wind power generation, marine propulsion power, and the like.

Description

technical field

[0001] The invention relates to the field of superconducting technology and the technical field of motors, in particular to a high-temperature superconducting motor. Background technique

[0002] At present, high-temperature superconducting materials are gradually entering the stage of industrial application, and the field of motor technology is a popular field of application. Compared with conventional conductive materials, high-temperature superconducting materials have the characteristics of high current-carrying capacity and low loss. These characteristics can greatly increase the power density of the motor and reduce the volume of the motor.

[0003] The high-temperature superconducting motor (HTS motor) involved in this patent refers to a new type of high-performance motor made of a coil made of high-temperature superconducting wire instead of a conventional copper wire coil as the armature winding of the motor.
