High-speed large-torque motor rotor structure and process of thermoelectric conversion system

Abstract

The invention relates to a high-speed large-torque motor rotor structure and process of a thermoelectric conversion system. The structure comprises an end cover shaft sleeve, an end cover shaft, a stop element, a sheath shaft, a magnetic core and a sheath shaft sleeve. On the basis of determining the size parameters of the end cover shaft sleeve, the end cover shaft, the stop element, the sheath shaft, the magnetic core and the sheath shaft sleeve, the processing of the motor rotor assembly assembling part is completed. Firstly, the end cover shaft, the magnetic core and the sheath shaft are assembled, secondly, the stop element, the end cover shaft and the sheath shaft are assembled, thirdly, the end cover shaft sleeve, the end cover shaft and the stop element are assembled, thirdly, thesheath shaft sleeve, the sheath shaft and the stop element are assembled, and finally, the motor rotor is integrally machined. The motor rotor has the characteristics of simple structure, good manufacturability, high rigidity, large transmission torque and the like, and the power density and the working reliability of the motor can be effectively improved.

Description

technical field [0001] The invention belongs to the structural design field of a closed Brayton cycle power generation system, and in particular relates to a rotor structure and technology of a high-speed and high-torque motor of a thermoelectric conversion system. Background technique [0002] As a new form of power, the closed Brayton cycle power generation system can convert thermal energy to mechanical energy through thermal cycle processes such as heat absorption, expansion work, heat release and compression with the help of a certain gas working medium under closed conditions, and utilize The motor further converts mechanical energy into electrical energy. The structure of a typical closed Brayton cycle power generation system mainly includes turbines, compressors, motors, regenerators and other components. [0003] As one of the core components in the closed Brayton cycle power generation system, the motor is the key component for the system to realize the efficient ...

AI Technical Summary

Problems solved by technology

After the motor rotor is equipped with a metal sheath, in order to realize the connection between the motor rotor and the engine rotor, a coupling structure is required, but the application of the coupling structure will not only increase the volume and weight of the closed Brayton cycle power generation system , it will also increase the difficulty of manufacturing and assembling the motor rotor and the engine rotor, especially for the high-speed rotor structure
