Abstract
High-temperature superconducting (HTS) linear motors adopt HTS magnets with high current density and strong magnetic density to substitute copper winding coils or permanent magnets in traditional linear motors, which can effectively reduce the weight of linear motors and improve the efficiency of linear motors under the same output power level. In order to better meet the requirements of high thrust density and strong equilibrium stability of the future ultra-high speed magnetic levitation train driving device, a neo-structure of a new type of bilateral multi-air gap HTS linear motor is proposed in this paper, and its stator structure, rotor structure, air gap and other key parts are designed. The corresponding electromagnetic transient model is established by ansys finite element method, which verifies its better normal stability during operation. The influences of superconducting coil loop current and coil turns on the maximum thrust of the motor are studied, and the causes of the results are analyzed. In order to further improve the thrust density of the motor, the electromagnetic thrust output characteristics of the motor are compared between the structure without a core and the structure with a core, and it is concluded that the coreless structure of the superconducting linear synchronous motor is more suitable for the operation of high thrust and ultra-high speed.
