Problems solved by technology

[0006] The use of high-temperature superconducting technology has obvious advantages, but in the actual operation process, due to the operating conditions and environmental restrictions of high-temperature superconducting bulk materials, it is difficult to effectively magnetize high-temperature superconducting bulk materials and obtain better magnetization effect, so that the technical solution using high-temperature superconducting bulk permanent magnets is difficult to implement

Abstract

The invention discloses an electromagnetic action device improving high-field large-current electromagnetic launch force and being used for a body to be launched, namely a high temperature superconducting launch rotor mechanism. The electromagnetic action device comprises the following materials and components: a high temperature bulk superconductor magnet, high temperature superconducting coils,a low temperature cabinet, refrigerating fluid and large-current electrodes. The electromagnetic action device is characterized in that via the high temperature superconducting coil magnets, the hightemperature bulk superconductor can be magnetized by adopting a stable impressed field cooling or zero pulsed field cooling magnetizing scheme; and the prepared rotor and an electromagnetic rotor actto generate greater electromagnetic thrust to implement launch. Through the electromagnetic action device, the technical difficulty of magnetizing the high temperature bulk superconductor magnet usedin the above scheme is effectively overcome and the magnetizing effect is obviously improved. The high temperature bulk superconductor and the high temperature superconducting coils form a whole in the design, so on the one hand, the intensity of the trapped field of the high temperature bulk superconductor is structurally improved, and on the other hand, the intensity of the magnetic field is improved from the current density of the high temperature superconducting material, thus greatly improving the effective field intensity.

Background technique [0002] Utilizing the effect of strong electromagnetic repulsive thrust, a strong electromagnetic action mechanism for driving or launching systems can be designed. Different from the conventional motor drive, this system has a short-term strong force, and can obtain a large acceleration and initial velocity instantaneously. As an example structure, a mover with permanent magnetism can be rapidly accelerated and launched under the action of an electromagnetic stator or an electromagnetic stator track. [0003] Although the existing electromagnetic launch systems have different structures, they are all based on the force of current and magnetic field or the fo...
