AI Technical Summary
Existing motor topology optimization methods suffer from computational complexity and jagged edges when considering no-load conditions, leading to increased manufacturing difficulty and difficulty in effectively handling complex operating conditions with multiple physics fields.
A motor topology optimization method based on the variable density method is adopted. By constructing a multiphysics material property interpolation model and combining sensitivity analysis and moving asymptote method (MMA) optimization solution, a topology optimization model under no-load condition is constructed, which solves the requirements of lightweight, high performance and high efficiency of motor structure.
A smooth boundary design for the motor structure was achieved, which improved the accuracy of motor performance calculation and manufacturing feasibility, and met the multi-physics field optimization requirements of the motor under no-load conditions.
