The invention provides a linear induction synchronous motor, which at least comprises a stator and a rotor, wherein the rotor comprises a thermal insulation device and a mouse cage, and the mouse cageis arranged in the thermal insulation device. The beneficial effects of the invention are as follows: the structure is simple, and the production and maintenance costs are low; because a high-temperature superconducting material is applied, the size of the motor is small, loss is little, and the efficiency is high; in the process of starting, the motor operates in an asynchronous mode, the characteristic of the motor is the same as the characteristic of a linear induction motor, and therefore, compared with a linear synchronous motor, the motor has the advantage of simple starting operation,and does not require the positioning of the stator; after starting, during normal operation, the motor operates in a synchronous mode, the characteristic is the same as the characteristic of the linear synchronous motor, therefore the motor has the advantages of flexible control and simple speed regulation, moreover, the efficiency is high during high-speed operation, and the motor is highly suitable for high-speed, long-time operation; quench protection is not needed, and the motor can automatically operate in the asynchronous mode even if conducting bars are quenched, and can still normallyoperate when the characteristic of the motor is degraded to the characteristic of the ordinary linear induction motor.
