This invention relates to the field of permanent magnet motor design and optimization technology, specifically a high-efficiency integrated permanent magnet rotor magnetic circuit optimization design system, comprising: a configuration module, a topology generation module, an analytical calculation module, an index evaluation module, a parameter analysis module, and a scheme output module. The system generates multiple candidate magnetic circuit schemes based on initial parameters and performs rapid magnetic field analysis and comprehensive performance scoring using the equivalent magnetic circuit method. The parameter analysis module performs parameter perturbation analysis on the preferred schemes, accurately identifying the key design variables that have the most significant impact on performance; the scheme output module then iteratively optimizes these sensitive variables as the main optimization objects. This technical solution transforms traditional high-dimensional global optimization into low-dimensional directional search targeting key variables, reducing computational complexity and optimization time, effectively improving the efficiency and accuracy of permanent magnet motor rotor magnetic circuit design, and ultimately outputting optimal configuration parameters and a complete magnetic circuit design model.
