The reactor type was comprehensively evaluated, and the high-temperature gas-cooled reactor (belonging to the fourth-generation nuclear energy system reactor type) won the first overall score and was considered to be the most promising reactor type for nuclear power plants in the United States and even the world in the 21st century.

Therefore, the technical indicators of the helium fan drive motor must be much higher than that of ordinary high-speed motors, and its safety factor, life, and endurance are also crucial, which poses a great challenge to motor technology research.

Due to the relatively large capacity of the helium fan drive motor, the real machine experimental measurement has great challenges in various aspects such as economy, efficiency and safety. It is difficult to realize the experimental measurement of the large capacity helium fan drive motor real machine. A simulated experimental test platform is needed to carry out safe and effective experiments that can feedback monitoring from time to time, so as to indirectly simulate the performance of the real machine of the large-capacity helium fan drive motor, and to design and optimize the real machine of the large-capacity helium fan drive motor.
