Interference Analysis and Assembly Process of Multi-layer Sheath Motor Rotor
This article focused on the design and optimization issues of high-speed energy storage flywheel motor rotors,proposing a multi-layer sheath structure to improve the stability and safety of motor rotors at high speeds.Firstly,suitable materials were selected based on the working conditions and performance re-quirements of the motor rotor,and the main structural dimensions of the motor rotor were designed.Subse-quently,criteria and methods for interference design were established to ensure that sufficient contact pres-sure was maintained between the components of the motor rotor under both static and dynamic conditions,a-voiding separation phenomena during high-speed rotation.Finite element simulation analysis verified that the designed interference can meet the material strength requirements,ensuring structural integrity and reliabili-ty.In addition,a detailed assembly process for the motor rotor was developed,and the feasibility of each as-sembly step was validated through thermal deformation and stress distribution simulation analysis.Especially in the final stage of shaft assembly,by optimizing the interference,the process difficulty was simplified,im-proving assembly efficiency and quality.The research results provide important theoretical support and prac-tical guidance for the design and manufacture of high-speed energy storage flywheel motor rotors,which is of great significance for improving the overall performance and reliability of the motor.
