Abstract

In this study, Markov chains are used to divide and model the failure modes of high-torque density motors and obtain a reliability evaluation model for the same. Thermal path method was used to verify the internal stress field of the motor, thereby laying the foundation for reliability evaluation. Furthermore, the changes in motor reliability under different torque densities were investigated. Finally, the optimization method for installing heat pipes and winding sealing is applied to high-torque density motors to enhance their reliability.
