According to the performance indexes of aeronautic motor and its requirements, the motor model is established by ANSYS-Maxwell 2D software and the air gap flux density is simulated and the cogging torque of the motor is weakened. The ANSYS-Mechanical software was used to simulate the optimized motor noise field. According to the permanent magnet brushless DC motor circuit model and the electromechanical actuator control schematic of the aeronautic motor, excitation is applied to the prototype to measure the sound pressure level of the motor, the simulation result is better. Simulation results and test values are close to verify the accuracy of the simulation results for the performance of aeronautical motor with a certain reference value.
