Problems solved by technology

However, the disadvantages in practical application are that when the train is stationary or running at low speed, the train has no suspension guiding force or the suspension force is too small to float the car body, so an auxiliary pulley system is needed for the support of the train and low speed running
This increases the complexity of the design of the maglev train system and track system and the stability of actual operation

Abstract

The invention discloses a hybrid high-temperature superconducting linear magnetic suspension synchronous motor, which comprises a high-temperature superconducting linear synchronous motor consisting of stators on double sides on a stander and a high-temperature superconducting coil rotor between the stators, wherein the stators on double sides are symmetrical about the high-temperature superconducting coil rotor. The hybrid high-temperature superconducting linear magnetic suspension synchronous motor is characterized in that the motor also comprises a permanent magnetic track stator and a high-temperature superconducting bulk magnet suspension rotor positioned above the permanent magnetic track stator, wherein the high-temperature superconducting coil rotor is arranged on the high-temperature superconducting bulk magnet suspension rotor. The hybrid high-temperature superconducting linear magnetic suspension synchronous motor organically combines the high-temperature superconducting linear synchronous motor and a high-temperature superconducting magnetic suspension mechanism together, is highly integrated, realizes friction-free suspension propulsion of the linear motor, has the advantages of large thrust, low loss, simple control, relatively small volume, light weight and no need of directional control, and can meet special application places such as magnetic suspension emission and the like.

Description

technical field [0001] The invention relates to a linear synchronous motor, especially a hybrid linear synchronous motor using high-temperature superconducting coils and high-temperature superconducting block magnetic levitation. The motor can be widely used in transportation, such as maglev trains, especially for electromagnetic ejection, Maglev launch of spacecraft, etc. Background technique [0002] At present, conventional unilateral and bilateral linear motors have been widely used in some fields. Among them, the unilateral linear motor needs auxiliary slide rails on both sides of the motor for the support, positioning and guidance of the motor mover due to the large normal attraction between the primary and secondary of the motor, which inevitably leads to sliding Friction increases the loss of the system. Similarly, bilateral linear motors also need auxiliary slide rails for the positioning, support and guidance of the mover, which also brings corresponding sliding ...
