Abstract: The reliability of motor in high speed operation is one of the key points of motor design evaluation. In this paper, the mechanical strength of high speed motor rotor is designed and calculated, and the structural parameters are evaluated by the change of steel sleeve and carbon fiber structure parameters to meet the requirements of high speed operation. On this basis, the electromagnetic characteristics of the motor are simulated and analyzed, and the design parameters of the motor are evaluated.

Key words: High speed motor, Reliability design, Mechanical strength, Simulation analysis
