Level Set Method Assisted Topology Optimization of Permanent Magnet Synchronous Machine
摘要
Aiming at improving material utilization and performance quality of electrical equipment, this paper investigates the level set method (LSM) assisted topology optimization to obtain new electromagnetic structure. The performance of LSM is validated by the magnetic actuator. Finally, the LSM topology optimization combined with size optimization is applied to improve torque properties of an interior permanent magnet synchronous machine (IPMSM). The no-load back EMF, torque ripple, and average torque of optimal design are compared with the initial design, which shows better improvement.
