Novel double-side linear synchronous motor employing high-temperature superconducting stacked magnet

Abstract

The invention discloses a novel double-side linear synchronous motor employing a high-temperature superconducting stacked magnet. The motor comprises a plurality of high-temperature superconducting strip stacked structures serving as a secondary side, a cooling system and a double-side opposite primary unit. The high-temperature superconducting strip stacked structures are blocky structures formedby stacking, packaging or hot melting of a plurality of superconducting strip sheet bodies. The cooling system comprises a low-temperature container filled with cooling liquid, and a plurality of mounting grooves are formed in the left side wall and the right side wall of the low-temperature container. The high-temperature superconducting strip stacked structures are embedded in the mounting grooves. The bilateral opposed primary unit comprises a bilateral iron core and a copper winding. A plurality of stator teeth are arranged on the inner sides of the left side plate and the right side plate. The copper windings are wound on the stator teeth in an integral pitch arrangement manner. The cooling system is arranged in an air gap of the double-side iron core, and each high-temperature superconducting strip stacked structure is right opposite to the stator teeth at the same side. The motor is high in thrust density, low in electric energy loss, high in loading capacity, high in operationspeed and convenient to magnetize.

Description

technical field

[0001] The invention relates to the technical field of linear motors, in particular to a novel bilateral linear synchronous motor using high-temperature superconducting stacked magnets. Background technique

[0002] Limited by the development of traditional permanent magnet materials, the maximum magnetic field generated by conventional permanent magnet materials is about 1.5 T; this has also limited the development of permanent magnet synchronous linear motors for a long time. The emergence of high-temperature superconducting magnets has improved this situation. How to apply superconducting magnets to linear motors has also become a research hotspot. According to existing reports, superconducting strips are cut into sheets and made into block structures, and after magnetization Finally, the magnetic field that can be generated is as high as 17.7 T. Using it to replace the permanent magnet material on the traditional permanent magnet linear motor can greatly ...
