To improve the performance and stability of an artificial heart pump,a permanent magnet brushless DC motor suitable for heart pump was designed and optimised,using a axial-flow magnetic levitation artificial heart pump as the research subject.The performance of the motor was validated using finite element simulation software to ensure it met design requirements.Comparative analysis was employed to study the cogging torque and start-up characteristics of the motor.Simulation results indicated that compared to traditional drive motors,the optimized cogging torque of this heart pump driving motor reduced by approximately 11.7%.The motor exhibited favorable start-up characteristics,effectively enhancing the operational performance and stability of the heart pump.This study provides guidance for the development of axial-flow magnetic levitation artificial heart pump driving motors.
