Abstract

The invention discloses a high-temperature superconducting linear induction motor driving apparatus used for linear traction. Secondary windings adopt high-temperature superconducting coils (102) put in a secondary iron core (101), and the windings are arranged at the same interval; each high-temperature superconducting coil (102) is a closed coil and singly fixed to a magnet yoke groove of the secondary iron core (101); the high-temperature superconducting coils (102) adopt cake-shaped structures and provided with runway-shaped sections; a secondary assembly is placed in a low-temperature container; an air gap (4) is formed between the bottom plane of the secondary iron core (101) and the upper surface of a primary iron core (202); and the conventional primary iron core (202) and the three-phase symmetrical windings (201) are fixed to the ground. The linear driving apparatus is small in volume, light in weight, high in efficiency, high in thrust and high in loading capability; the reliability of the apparatus is greatly improved and the service life of the apparatus is greatly prolonged; and the high-temperature superconducting linear induction motor driving apparatus can be widely applied to cargo sorting systems, linear induction doors, lathes, trains, metros and the like.

Description

technical field [0001] The invention provides a linear motor drive device, in particular to a high temperature superconducting linear motor drive device for linear traction. Background technique [0002] The linear induction motor drive device relies on the primary three-phase winding to generate a traveling wave magnetic field, and induces a current in the secondary, and then the motor will make a linear motion under the action of the ampere force, so that the thrust can be directly generated without an intermediate conversion mechanism, which is This makes it more advantageous than traditional rotating motors in industrial applications. Therefore, since Wheatstone invented the first linear motor in 1845, people have looked at it differently. Especially after the discovery of high-temperature superconductors, the development of linear motors has entered a new stage. With the continuous improvement of superconducting material preparation technology, the performance of high...
